How men fall in love – The stages of love

A series of chemical reactions in the brain.

If we want to get really basic, that cocktail of chemicals that seem to dominate most human interactions: dopamine, testosterone, and a few other unsung heroes flood the brain. Or, if you're not into science, let's just call it black magic, Cupid's arrow, or whatever the fuck happened in that Lindsay Lohan movie where she switches luck with Chris Pine (which, to be fair, may have also happened in real life on an on-set accident who knows). Even still, that only really answers the what happens, but it doesn't explain why it happens in the first place. What triggers these chemicals? It's really conjecture the second we stop talking about the drinks our brain-bartender serves our body, but there seem to be a few old standbys.

Men appreciate a lot of women on a daily basis. 

They try to steal second glances or get a girl’s attention all the time. But it’s not always a success, either because he’s not trying hard enough or because the woman’s just not interested in him. The infatuation stage of how men fall in love is also the wooing stage of love for men in the dating game.

A man may appreciate a lot of women, but he doesn’t really get infatuated by all of them. If he appreciates a woman, and is interested in wooing her or pursuing her, he enters into the infatuation phase.

A man may pursue a woman in various ways, but if she doesn’t accept his advances he usually forgets the girl as just another attractive girl he wanted to go out with. It’s easier for a man to like a girl one day and forget he ever liked her the next because he has so many stages to deal with before he even makes up his mind on falling in love.

He Feels Like He Can Make Her Happy

“Ultimately what men and women want is the same—they want to feel connected, they want to feel attraction, and to experience passion. A man is looking for a woman with a smile. Men bond with women when men feel successful in making them happy. A woman needs to focus less on making her man happy, and focus more on how he makes her happy.”

The Attraction

If an attractive girl reciprocates to a guy’s advances, he enters into the attraction stage of love. Until this stage, a guy can walk away from a girl without any pain or heartbreak even if the girl rejects him. He’s not really trying too hard, and he’s not really fallen in love to care about a rejection when he’s just trying to get lucky.

But if a girl does show the slightest sign of reciprocation or interest in the guy, or even if he assumes she’s into him, the guy digs deep into this stage, the attraction stage. In this stage, he decides to pursue the girl and make her like him.

He feels emotional intimacy and a deep connection

Intimacy is another ambiguous concept... if love is the bread, intimacy is the deli meat that makes the whole thing a sandwich. That's a statement that seems to make perfect sense at face value, but is probably also incredibly confusing when you start to examine it... just like love. But if, for whatever reason, he feels he can deeply trust you and talk to you and open up (especially if he's got a hard time doing that with others), that can really get him on the path to love. Intimacy is the foundation upon which you build you house of love and then you fill that full of deli meat, which is also intimacy. Relationships are a house full of meat. Maybe you were there for him after a death in the family, or you stuck by him when he felt like no one else would as he struggled to find a job. There are a lot of ways to "prove" you've got a deep connection, and they don't even have to be that intense. It could just be that he loves talking to you about anything and everything and never feels judged.

When She’s Open to Love

“A man will fall in love when you give off the signals that you are truly looking for—and ready for—lasting love. The cues you give off are everywhere: Do you allow yourself to be vulnerable and really let him see who you are? Are you confident in your sense of self? Do you know what you want from life and where you are headed? Another key element in showing you’re ready for love is having a strong sense of respect, both for yourself and for him. Men want to know that you think they are worthy of love. They also need to see that you know you are deserving of love. Men will fall in love with someone who is open, receptive, and ready to be loved.”

He feels supported

There's a lot to be said about guys who find women that remind them of their mothers. And sure, blah blah blah Oedipus blah blah blah gross and also something about Freud. But what's really there is a desire to feel safe, to feel supported, to have a "life partner" in the truest sense of the word. He wants someone that is going to make him feel comfortable, to complement his weaknesses. In the least gross way possible, your life partner really is meant to pick up where your parents leave off, so it's not crazy to think there's some overlap there. And support manifests itself in tons of different ways. It could mean you're the one with the great job and the income, it could mean that you're the one taking care of the kids and making dinner, it could just mean that he trusts you implicitly and knows you'll always back him up and never leave. It could mean that you challenge him constantly to do better, to be a better person.

She Says “Yes” to the Game of Life

“Finding a person who fits into his life without huge disruptions is important. Men may like to ogle high-maintenance women, but they’re not the women they marry. A willingness to say, ‘Yes, I’ll try that’—whether it’s trying exotic food he likes, sports he plays, places he wants to go—makes a man fall hard. It’s not to say that you have to love everything he loves… but at least you’re willing to try!” 

Wrapping up

The sex is great. Don't laugh, sex increases dopamine levels, and that's a key ingredient in the chemicals that promote that loving feeling, according to Dr. Helen Fischer. So great sex really can make him fall in love. So those times when you see two people together and think, "I don't get it. It must be really great sex." you could very well be right.
“No other emotion seems more mysterious than love. At its core, falling in love is driven by our desire for happiness.
