Unbreakable heart finally breaks

I can't stand this anymore and I wish that I didn't have these feelings for this person. My heart and mind tell me two seperate things and they are both opposites. My heart tells me that I really really like this person and that it would be ok to tell him how I feel and to do something about it but my mind is putting up a neon sign that says he is off limits and that he has a girlfriend. We were sitting together today playing video games and everytime he touched my hair I enjoyed it maybe a bit too much and when we were laying on the couch and his head was on my shoulder I couldn't help but feel comfortable and that nothing in the world is going wrong. He is like my best friend and I could tell him anything but not this especially when he is doing so well with his girlfriend. For goodness sake I was on the phone crying to him one night. We both miss each other alot when we leave. I think if we didn't end the hugs they would go on forever and I wouldn't mind a bit. He said that his girlfriend would get jealous but I don't really care that is her problem. Oh well I guess my piece of my heart will always be his even if he doesn't know it. My future husband will have to deal with it.
