I'll take a stab at this.
I'm a man, and I don't think we feel love in the same way women do.
Firstly, I don't think love itself is one emotion. It's a whole bundle of them, both negative and positive, rolled up into one. It's attraction, jealousy, affection, a need to provide, a need to feel cared for, companionship, happiness, grief, fear, and a whole load else besides.
And all these emotions in differing amounts make up love in all its forms. I.E. You love your friend for the companionship they provide, but you don't (usually) feel jealous when they have other friends. You love your Mum because they care for you, but (hopefully) attraction doesn't factor into that relationship at all!
And finally love with a partner is the most complete form of love. It's the one where you feel almost all of the range of emotions associated with it.
The problem is that men are emotionally stunted. We're discouraged from childhood from feeling a whole range of emotions. "Boys don't cry", "You're too old for a hug", "Don't be scared, you're my brave boy".
Periodically, someone will ask on Reddit "Whats a thing that women don't know about men", and pretty much every single time the most upvoted response is some variation on "The last time I was complimented was five years ago and I still think about it some times"
We're told from birth that we shouldn't feel things, so we push them down, and sooner or later we forget how to feel them. So for men, love is very much stripped back. We're allowed to feel attracted to someone, we can feel jealousy and possessive, we understand that we're meant to be the provider, the strong one, the brave one.
But happiness, companionship, wanting to feel cared for and appreciated, these are all muted for us. We're meant to be stoic, comfortable by ourselves, the idea of asking for a hug horrifies us!
And we can do fear, and grief, but we've been taught to hide them, so they tend to come out as anger, because we're cross with our selves for being sad, and weak.
In short, we're broken.
In some cases that means we don't love enough, or we're not scared enough of losing what we have. So we lie, we cheat, we do things that we know will upset our partners.
And in some cases the negative emotions involved in love overwhelm the positive ones, and men become posessive, controlling, abusive.
Things are changing I think. I'm 40ish, and work with a lot of people in their early 20s. They're a lot more open with their emotions, a lot less scared to say when they're unhappy, or worried. It'll be interesting to see how that translates into relationships in the future.
So to sum up: The Patriarchy! Fucking up life for men just as much as it does women.
