Dating Disaster

I am a dating disaster. I am a failure. I get attached too easily. I keep dating non-christians and it really doesn't work. I just stopped seeing a guy tonight, who wasn't a christian and he shook my hand goodbye, it was so cold. I wanted to scream, damn it why couldn't you have been a christian. Why? It's not fair. I actually really like you. In some way I should be happy that I saved us both alot of pain. Why do I feel like crap? I'm unable to just date casually without getting attached. I'm just incapable. I suck.
