I might be having a relationship problem?

I'm having a girlfriend problem. She never wants to do anything with me. I mean, I try to do stuff with her... I stand outside her house at night quite often and sometimes I break in and go through her room when she isn't there (because she doesn't want to be around me). I send her gifts like chopped locks of my hair or pictures that I take of her when she isn't looking. I sent her a really nice machete that I bought at a surplus store and sharpened myself along with her picture. It's hard to take the pictures because she runs away whenever I get close, and she ran track in high school and is pretty fast. I tried to chase her and she got away. Also, she may be a virgin and I want to change that a lot. Is there anyway to have with her without her knowing...
