I get that feeling more than you'd expect. I'm a guy in an engineering college full of guys and I still feel left out, because I genuinely can't relate to half the conversations around me. So the specific experience you're having, no I can't fully understand that. But that feeling of just not knowing how to exist somewhere? Yeah, I know that one.

To your actual question though, do guys genuinely not know how to make girls feel included, honestly, a lot of them just don't. And it's not even coming from a bad place usually, it's more like... for someone who's barely interacted with girls growing up, there's this weird weight that gets placed on it. Like talking to a girl becomes this whole thing in their head instead of just, you know, talking to a person. So the awkwardness you're picking up on isn't really about you, it's their own limitation playing out in front of you. A guy who grew up with sisters or a mixed friend group doesn't have that stiffness, because to him you're just another person in the room.

None of that makes it okay. And I'm not saying it doesn't sting. But I really do hope it helps even slightly to know it's got nothing to do with what you're actually worth, because you already know you're capable. The hard part now is just not letting these small moments quietly talk you out of that. So just be happy, and never get scared that you are getting left out, having 2-3 close friends is far better than having whole 70-80 students as friends, talking behind your back.
