- 00:04Let me tell you about Claire.
- 00:06Claire is 42, a sharp executive.
- 00:09On paper, her marriage is perfect.
- 00:12And in my office, she whispered,
- 00:15"I feel nothing."
- 00:17And then she asked me,
- 00:19"Am I asking for too much?"
- 00:22Max is 38,
- 00:24a founder who has lived happily with Allie for the past four years.
- 00:29And yet, he found himself in my office asking me,
- 00:33"Do you think she's the one?"
- 00:35We all carry stories about how love should be, feel and look like.
- 00:41I see this through the lens of my work as a relational psychotherapist,
- 00:46psychosexual therapist and social psychologist.
- 00:50In the past 20 years,
- 00:52I've helped more than thousands of people across the world
- 00:56to help them make sense of their relationships
- 00:58from the most intimate spaces
- 01:00to the most public ones.
- 01:02Today, I want you lovelies to look at me as your relationship architect.
- 01:08Because I'm here to offer you a blueprint that is evidence-informed
- 01:13and is going to introduce you to a whole new model of love
- 01:16so that you can develop the loving relationships you desire
- 01:20without second-guessing yourself,
- 01:22the other person or the relationship.
- 01:25I hope you're ready.
- 01:28So my colleague and I studied 450 couples
- 01:32who've been together anywhere from one
- 01:34to 40 years.
- 01:37And these couples showed us six essential ingredients.
- 01:42And after we analyzed 180,000 data points about them,
- 01:48we came up with these six ingredients,
- 01:49but also, surprisingly,
- 01:51we found out about a whole new model of love
- 01:54that I call “emergent love,”
- 01:56because it can only exist
- 01:58when the six ingredients
- 01:59that are essential for thriving relationships
- 02:02are present.
- 02:04Imagine it as a warm and cozy fire
- 02:07that can only be alive
- 02:09when all the essential elements are there to keep it going.
- 02:13Now when I walk you through these six ingredients,
- 02:16you might say, "Oh, they sound familiar,"
- 02:18but there's a twist
- 02:19because our thriving couples embody them and define them differently.
- 02:24Number one is attraction.
- 02:27For thriving couples,
- 02:29attraction is way beyond sexual chemistry.
- 02:32It's only one of the reasons that they come together.
- 02:34And in this way,
- 02:35attraction is a renewable energy
- 02:38because it wants you to be around the person
- 02:41and explore new ways of being with them and re-knowing them.
- 02:47On the other hand, sexual chemistry is a fleeting biological desire
- 02:52that can fizzle out
- 02:54when the initial infatuation phase is over.
- 02:59I'll tell you what,
- 03:00when the novelty part of the relationship is over,
- 03:03if you want to chase the chemistry,
- 03:05it's as if you're tickling yourself.
- 03:08It just doesn't work.
- 03:10And then we are convinced
- 03:11that we fell out of love with our loved one
- 03:15or we chose wrong.
- 03:17There is also a daily practice that we observe in thriving couples
- 03:20that they didn't name it,
- 03:22but in social psychology we have a term for it.
- 03:24It's called reciprocal liking.
- 03:27What it is basically,
- 03:28is if I think that you like me, I like you back.
- 03:32It's more likely that I like you back.
- 03:35Now these daily signals need to change as we change over time.
- 03:40Really think about it.
- 03:41Between diaper duty and deadlines,
- 03:43where is that signal that says, “I like you?”
- 03:47“I’m into this version of you, now.”
- 03:51Number two is respect.
- 03:53Respect literally means to look again.
- 03:56So basically, it's the opposite of taking anyone, including yourself,
- 04:00for granted.
- 04:02And obedience,
- 04:03walking on eggshells, is not respect.
- 04:06They are fear.
- 04:09Thriving couples have basic etiquette.
- 04:13They say hello in the mornings.
- 04:16They say good night before they call it a night.
- 04:19They don't interrupt.
- 04:21They don’t walk away mid-conversation.
- 04:24And they don’t cover up sarcasm as humor.
- 04:28I often hear, “I’m not respected by my partner.”
- 04:31And I ask, "Are you respectable?"
- 04:34And there's a pause.
- 04:36I say, "Look, do you live by your own principles,
- 04:38or are you the first person walking all over them?"
- 04:42Do you communicate your boundaries as invitations
- 04:45so the other person knows how to be around you
- 04:47lovingly, firmly and on time,
- 04:49or as passive aggressive ultimatums?
- 04:52And do you equally have regard for the other person's boundaries?
- 04:56Thriving couples are both respectable and respectful.
- 05:02Number three is trust.
- 05:04We found that trust has two main pillars.
- 05:08One of them is consistency, and one of them is reliability.
- 05:13So you have to really be able to have both.
- 05:17Now thriving couples know that trust is built and rebuilt
- 05:23based on little promises kept over time.
- 05:26Not grand and expansive and expensive apologies.
- 05:33Think of it this way.
- 05:35That you need to show up for one another,
- 05:37no matter how big or small the stakes are.
- 05:40You can't leave the other person hanging.
- 05:42Think about that unpaid bill.
- 05:44Think about the second drink you chug down
- 05:47and you don't even remember it.
- 05:49Think about the private story that was shared public.
- 05:53Think about the harmless DMs and likes.
- 05:58Number four is compassion, not empathy.
- 06:02If empathy is feeling with the other,
- 06:05compassion is feeling for the other without losing your own ground.
- 06:10Our couples told us
- 06:11that overemphasizing and overidentifying can kill your relationship,
- 06:16can really drain your relationship.
- 06:19Yes, there are moments
- 06:20that you would like to commiserate with each other
- 06:23or feel those juicy sensations
- 06:25when you have erotic empathy with one another.
- 06:27But for daily lives, everyday life,
- 06:30compassion is the default for these couples.
- 06:34Picture this.
- 06:35I come home upset.
- 06:37You match my intensity to the level that you lose it with me.
- 06:41If we are both bleeding, who gets the band-aid?
- 06:45So thriving couples can be there for the other
- 06:48without making the scenario about themselves.
- 06:52Next one is shared vision.
- 06:55You need to know where you are going individually and as a couple.
- 06:59At least know where you don't want to end up.
- 07:02Otherwise, your resources will be scattered,
- 07:04and resentment will be inevitable.
- 07:08Thriving couples have plans for their days, weeks and years ahead.
- 07:13They name a destination,
- 07:14and then they prioritize their resources of time,
- 07:18energy, attention and money,
- 07:19and they commit to them.
- 07:21So their daily choices are strategies, not tug of war.
- 07:26They also negotiate often what movies to watch tonight.
- 07:31They compromise sometimes.
- 07:33This holiday at my parents', the other one at yours.
- 07:38They sacrifice rarely.
- 07:41For example, let's have this relationship long-distance for two years
- 07:45until your degree is over.
- 07:48They make it time-bound.
- 07:50Specific, rewarded, not expected.
- 07:54Last but not least is the loving behaviors.
- 07:58Loving behaviors show us you don't fall out of love.
- 08:03You fall out of loving.
- 08:06So one thing that we learned is
- 08:07loving, thriving relationships is not unconditional or a given.
- 08:12When was the last time that you went out of your way for your partner?
- 08:18Do you give each other the benefit of the doubt?
- 08:21Thriving couples are tender with their touch, with their words,
- 08:25with their presence,
- 08:26and they make them exclusive and specific to each other,
- 08:29even if other people are in the mix.
- 08:31So, for example, if they say "honey,"
- 08:33their dog and partner and mom and neighbor,
- 08:35everybody don't show up all at the same time.
- 08:38(Laughter)
- 08:41There you have it, lovelies.
- 08:43I offered you an evidence-informed blueprint to build thriving relationships
- 08:49so love has a chance to emerge.
- 08:51You build what fits your life.
- 08:54And tonight we talked about coupledom.
- 08:56But trust me, I've seen it over and over again,
- 08:59if you master these six ingredients,
- 09:02you will rise in all of your relationships.
- 09:05Because the way we do one relationship
- 09:07is the way we do them all.
- 09:09And if you're going to take one thing out of our time together tonight,
- 09:13let it be this.
- 09:15Everyone can
- 09:17and deserves
- 09:18to be in the loving relationships they desire.
- 09:22Thank you.
- 09:23(Applause)
