Your boyfriend thinks you are a stuck up and you should grow up?

Take a good look inside yourself and be 100% honest.

Are you stuck up, snobby, egotistical or immature? If the answer is no then, I don't think your boyfriend is doing a lot for your selfesteem, not to mention being rude and ultimately incorrect anyway.

However if the answer is yes. He probably finds it easier to look past your flaws than most people, maybe he is trying to let you know that if you don't change your attitude it will always be hard for you to have healthy relationships with other people whether they be friendships or more.
