Numero Uno

So things aren't going well right now. I had sex with my girlfriend in September and I've continued to feel more and more guilty. It's been slowly tearing the both of us apart. I know that God wanted me to wait for marriage to have sex. I did it anyway. She wanted to do it too. I'm not blaming her because I made the decision to go along and do it. I've had guilt on my shoulders for months. Now it's finally becoming apparent that it's not where we wanted this to go. I'm going to have to make a hard decision now. I'm afraid to do it. I know that God forgives me but I have the hardest time forgiving myself.
