I'm totally lost , do I love her?

I'm tired of things happen to me recently, come first is love, or just a strange relationship between me & a girl, for some reasons, I can't have a girl friend now and I'm sure want my mind in a "clearly" status, I don't want to think about girl or love (just 'cause I'm having a project which ask me too much time and labour), but time pass by, I realize that I'm can't against the feeling inside me ... yes, maybe I love her, maybe I need to tell her that, but I can't do that , and I'm totally lost now, I don't know what should I do ? I just want to be myselft, like just before everything happen
I need to forget HER.

You dont need to forget her, what it seems like is that you are in love with her otherwise you would not be feeling this way. Yeah time is needed to let a relationship work but maybe she can understand that you may be spending most of yr time away from her. Love has no limits so you should go after her not away from her! Follow yr heart man! Pull the project out of yr decision!!!
