What should I do now?

Emabarrassingly enough, I met a guy on the Internet and then agreed to meet him in person. He was great. He is attractive, smart, funny, and adventurous. I had a wonderful time, but I still don't wan tto end things with the other guy I am dating. I know that he is a poo poo head and I keep complaining about how he treats me, but for some reason, I can't let him go. There is something keeping me there and I don't know if it's God or if it is just me being lonely. There is no way I can pass up on this other guy. Maybe God is trying to test me to see what I am going to do in this situation. Am I going to stay with the jerk or will I go with the nice guy? That answer seems like it would be pretty simple to answer, but for some reason it isn't. Am I just destined to live my life going from one asshole to another?
