Theres this girl that likes me, I know cause alot of people told me and she told them, plus theyre are trustable, and I think I like her too, but she never talks to me anymore, and acts as if she hates me, plus shes trying to avoid me.
What do I do.
Typical. ;3
Having had much experience with this sort of thing, the best thing for you to do would be to just ignore the immaturity. 'Cause, I mean' let's face it. That's exactly what she's doing; being immature.
Next time she's 'mean' to you, just act... well, normal. Try to hold a decent conversation with her, and ignore anything out of the ordinary. I don't mean to sound like I know everything, 'cause I most certainly don't, but chances are, she's treating you like this because she doesn't know how she's suppose to act around you. Why? I have no clue, but that's the most logical explanation I can come up with.
As I've already said, just talk to her. Don't feed in to her little games; sooner or later she'll learn that it's alright to talk to you normally, and she'll learn to be herself around you. (hopefully)
