SO, my friend just saw a guy I'm interested in bringing a girl back to his apartment, food all bought, and then they leave together again in a few moments, only now he has a backpack. The girl was wearing a short skirt.
Friend said that when he saw her (my friend) he tried to act like he wasn't that tied to the girl, but they seemed like they are really accustomed to each other, no need for formalities.

I'm feeling pretty bummed. I guess next time I shouldn't talk to him, but I'm still kidding myself and hoping it isn't what it looks like.

What do you think, 4-ch? Would this stop you from talking to him? I worry if I get more emotionally invested it's going to end up ugly, for me, but I don't know how to stop feeling bummed right now. What should I do?
