Found out my OH cheated on me in September he had been having an affair since July and it started at an office party with a woman who still works there. His Christmas Party from work is tomorrow. He has offered not to go or to go and drive and not drink but my head says this is the wrong thing after all if he has a couple of drinks and goes back to her our marriage isn't worth much. So I have said to go but my anxiety is out of control - have I done the right thing and how can I get a grip on myself I feel back to feeling how I did when I found out he was cheating.
