What do I do, I can't stop thinking about her, I can't stop messaging her.

The thing is, I do like her, and I like her personality, her look the way she is and I love her laugh. and I really wanna tell her I do, but I don't know how she'll take it.
yes its a girl I like her and we were together yesterday, and to be honest I haven't been able to get her out of my mind all night were going to see a movie thursday but I think its just friends,
but yesterday she was rubbing my back and she did have her hands in my pockets and when I was sitting on her lap we were holding hands am so confused though
in text messages shes been calling me sweetie and cute but idk it could just be her
but I really want to get to know her and from what happened yesterday I think she likes me but am unsure cause she could just be like that with everyone I guess
I really don't know what to do....

Well I would say if she is holding hands and letting you sit on her lap than she likes you. plus if she did all that and is still going to the movies with you. Than I would say "yes" however, if you are having feelings for her and are not sure how she feels the best bet is to be honest with her. That way you know right away. The best better though is honest.

close ur eyes for a moment think that u don't like her...seems u can't!
then think of the opposite that she don't like u how to be sure??u'll try to know more about her and then find out what could she like who she knows,,,,
with that if she still had no special person u can know a way to make her love u,,
and if she do u can just think that what she did was to tell u that u r like her small child maybe,,,
I don't mean she may heat u but to think of the worst chance u can b ready and not get in bad situation what ever the result is...
My idea is that she likes u and she is that type who like romance...
