I recently ended my relationship of three years on and off. He was hurt, completely heartbroken.....balled like a baby. I ended it because I had ran into an old friend and I realized how unhappy I really was in my current relationship. I never laughed or felt completely comfortable around him. And this other guy is the biggest sweetheart, like paint my nails and always making sure I make it home okay kind of guy.

Anyways a day after we broke up, I got a little tipsy and had sex with my old friend. We've been hanging out and talking but only for like two weeks. Things are great but Im not sure if I'm ready for a real relationship again. I need me time but I don't exactly want to end what we have going on.

However, I ran into my ex at the bar last night and I was really drunk. He started crying again and I ended up holding him for a while and then we went back to my place and had sex. It was great, but it shouldn't of happened. I totally regret it now, and I feel like such a slut but now my ex thinks we're gonna get back together.....I told him it shouldn't of happened and that I was honestly just really really drunk but he's not getting the picture.

Should I tell him about the other guy? Or will that do more damage then good at this point?

And....should I tell the other guy about my ex and I?
