Name changed because I feel utterly humiliated. Today I was checking the joint account and saw a transaction to match.com, DP uses the same passwords for everything so I tried to log in as him to see if he did have an account and found that he spent 3 weeks chatting to various women on the website, including asking two of them for their telephone numbers. I confronted him and his excuse was that he was 'confused' and stopped when he realised how much he had to lose. He doesn't think it's that bad because he "didn't do anything". I feel utterly sick and humiliated. I still had a niggly feeling that he wasn't telling me everything so I had a look in his email and found that he had started another online dating profile back in June. Again, he says he was 'confused and having doubts'. In a way I could understand if he went out, got drunk and kissed someone, but this is plotting to be unfaithful. We're expecting a baby in four weeks time and have a 3 year old, I don't know whether to just pack our stuff and go. AIBU to think this is just as bad as being physically unfaithful? I'm sorely tempted to take my keys and scratch up his precious car.
