I don't have anything valuable, not a car, or cool games, or even good/witty jokes.   
So why then, do I feel like the people who eventually like me, for whatever reason, will stick around and try to be friends?  
I guess More than anything, at this time, i am referring to my ex. We only dated briefly, after i allowed a "home wrecking" type situation to enter my world, (she was the 'home wrecker')  She always said she liked me. But after time, i realized we shouldn't/couldn't be together, so i left town.  Its been a year, and lots of ups and downs. but she still is around, kinda, talking online, playing games.  I did like her, a lot. she was cute, smart, funny, hot, i mean i was attracted to her for sure. plus she was odd. i liked that. she was respectful of my boundaries, and feelings.  
All this time later, she knows how i still feel for her. and sticks around saying she makes a good ex-girlfriend/friend. I feel so sad because i dont know why shes keeping me around. Im sort of terrified. I dont want to reach out to her because im not sure what the difference is, between girl who is a friend and Girlfriend. Ive never had a girlfriend i didnt fall for.  So i dont know how to act. i feel like part of me is staying around to keep her just incase she still likes me like that. But i dont wanna treat myself like crap by sticking around hoping. Im scared of her friendship and i dont know why. she is a nice person. I had a nightmare about her being an evil villain and breaking my heart. we aren't even together.  
Im just scared im being used?  
Sorry for the rant.
