No progress

So I met a girl. I actually met her on this site. And she was really nice. We had so much in common and i always got butterflys in my stomach when I talked to her. It didn't bother me that she lived in another state. I just liked her. A lot. But I have a problem. I don't think I am worth it. I don't think I deserve to be happy, or loved. Whenever someone starts to get close to me, I back away and I get scared. That's what happened with this girl. We were texting like crazy, and even flirting, and then I just stopped talking to her, Becuase I was afraid she would figure out that I am just a coward and that she wouldn't want me. I know it's what will happenIt has before. I taught myself a very long time ago not to get attatched. It makes me sad to think that I will always be this way. The only word that comes to mind is, unlovable.
