Why do christian guys act so weird?

[BritneyS]

I was dating this guy. He was so excited about being with me and talking about having a long relationship...wanted to take it slow so that it would last a long time. I admit we kinda rushed things and had sex a little early, but afterwards he just seemed overly excited about our relationship, calling nonstop....as much as 5 or 6 times a day. Saying that the sex was the best he had, and was great, telling me how beautiful i was and how i was the prettiest and smartest girl friend he has had, and he was looking forward to having me for a long time. We are both christian and i know the sex things is not good, it wasn't suppose to happen. But like i said afterwards he was perfectly fine with it and actually started calling me more. he called sunday begging me to come see him after church and then all of sudden texts me on monday saying " he wants to work on his relationship with God, and doesn't want me to call or text him again, saying he wants to be single" Less than a day before the break up text that i just described, he was telling me how he loved me and cared about me so much, and couldn't get me out of his mind. What exactly happened because i am really confused? I know that maybe the sex thing rushed things, but he was the one that got all carried away with it, and started saying " i love you " afterwards, and calling nonstop. He was the one that made it seem like the sex was okay and kept talking about it nonstop afterwards like it was just the most wonderful experience. I would have been okay never having sex again. I really dont understand, and i am a little hurt, cuz i just got this text yesterday. I have asked God for forgiveness, i dont know what else to do......
