Ok so in detail:

He (says) he got drunk and cheated on me with her and then came and visited me at work and kissed me with her stink on his mouth. He says he's sorry but then turns around and accuses me of all kinds of crap (cheating-themed) that isn't even close to true.

We've been married only about 8 months now and together for just over 2 years. He has 3 boys with her and I'm just disgusted. I guess I know what I need to do but I'm basically unwilling to do it.

Is my first marriage really over already?
