My girlfriend and I have been together for 2 years. We've had an occasional fight here and there, but never anything serious enough to break us up. My girlfriend has sworn off sex until she finds "Mr Right" while I've had several partners in the past, though I told her every detail before we started dating. Several of our fights were about the fact that we don't have sex, but always ended in her adamantly sticking to wanting to find her soul mate.

A few days ago though I went out with a work colleague and we had a few drinks. I told her about this and how it was making me feel. Next thing I know, I am waking up in a hotel room with her several hours later. I immediately regretted everything and cut all ties to her. I feel like absolute shit now. I don't know why I betrayed my girlfriend and I want to atone for what I've done. I'm scared that if I tell her, she will cut all ties to me and do everything in her power to make sure everyone I know and love does as well. I know the majority of people will think I'm an insensitive shitbag, and I fully agree. But is there a way to atone for what I've done? I'll do anything.
