Why does she never invite me?
Explain to her how it makes you feel.
Reply:Maybe she's feels different when she's hanging out with yu from when she's hanging out with her friends. Many people are like that, its nothing serious, i mean unless yu really want to, you can be open and confront her about it. My boyfriend don't like it when i hang out with him and his friends because it'll feel different like he'll have to be in two places at the same time. Giving me attention....as well as his friends so yea..
Reply:sometimes girls and guys feel like their boyfriends/girlfriends are more like "friends with benefits". You just need to tell her that she should like you enough to let you meet her friends and if not than thats just not fair.
Reply:um, talk to her. most guys hate doing stuff with the girls, she might just assume the same with you. if that's not the case, then she might be embarrassed to be with you.
Reply:I guess she is still trying to hide you from her friends, but you should have at least met her best friend. Look at it this way her friends is her guarded secret and she doesn't want you to mix. However, ask her about it. If she is not ready to share that part of her life with you, then sorry to say, she is not the one for you.
