I have name changed and I think I know what most of the replies will say but I want to know whether or not I'm being a complete idiot.
So the background is that me and DH have been going through a bad patch (together over 20 years and no DC at home). He has MH issues, had a breakdown and moved out a few months back. We've been working hard to improve the relationship and his MH has been improving. Of course, I suspected an OW in the beginning but there was never any evidence and no one crawled out of the woodwork once he was in his own place. Anyway, fast forward a few months and we seem back on track, really enjoying being together and committed to living together again.
Last night though he made me think he was at his flat but I had this gut feeling he was out. It turns out I was right. I drove to the station just after the last train turned up and there he was walking back. Worse still, he was on his phone chatting away to someone at nearly 1 am.
I pulled up. He hung up. We talked. He said he didn't tell me he was going out because I would have kicked off. He is partly right that I would have been uncomfortable about it but not because I don't like him going out, it is because of the fact that he is always massively evasive when going out with that group (friends from work, male and female). The person on the phone was one of the women who apparently wanted him to phone to say he'd got his connecting train ok. Not sure why, he's a big bloke and old enough to catch a train on his own. Apparently she is concerned about him because of his marital situation (she didn't seem to know we were ok again).
I said he'd misled me and hidden the truth and also been completely inappropriate to be on the phone to another woman at that time of night.
He doesn't really see that he's done anything wrong because he says he knows that he didn't have any inappropriate motives and now seems to be acting like I should be the one in the doghouse for being angry even though I have exposed the lies and what I think is probably an emotional affair.
Every time I close my eyes I just see him walking along on his phone smiling...
I'd really like to know some other opinions on this. Am I overreacting by being annoyed or under reacting by not ending it?
