Do you think it's okay to tell my crush to gtfo if she talks about other guys?
You're going to tell off a crush just because she talks about other guys?
Yes, I want her totally to myself.
Dude, I understand you have a crush on her, but have you even dated her? It's presumptuous to make demands on someone just because you're in to her when you don't even know if she sees you as more than a friend.
I'm in love with her and I can't stand to see her interacting with someone else.
Think about how you'd feel if a random guy had a crush on you and threatened you if you tried to date a woman. I'll bet you'd hate that and I'm sure that your crush feels the same way.
