I know a girl likes me (Im a 15 year old boy) and I think I like her but I'm afraid to ask her out. Our friend brought us together and was like "Ask her out". I just froze and then she had to go. The reason I think I do not want to go out with her is because 1.) I do not know how to act or what to do. When I went out with another girl, we were good friends until we went out. I got really shy. Then she broke up with me and things were weird. Me and this new girl talk a lot and flirt. I am really talkative normally to her. Once I found out she liked me, I barely talked to her. I started to talk to her more but still not a lot. If I was to go out with her, I would ruin our friend relationship. What should I do?
