A few weeks ago I was at a colleagues house warming party. One of the seniors is leaving so we decided to message an ex colleague to let him know that a position would be available soon and that he would be perfect for it. The ex colleague is gay. I mentioned it to DH and he was raging that I had messaged another man. All a bit odd but I put it down to him having a bad day. Last night was another works night out. I got a lift home with a female colleague and a male colleague. Male colleague is in a happy ltr with a baby on the way. DH knows this. Both of these colleagues live in my area and no one was drunk. DH is raging that I travelled home with a male. He isn't talking to me. We were alone for approx 1 minute after dropping off female colleague. It would have been extremely odd for me to get a taxi myself when we all live so close. Not to mention more dangerous for me to be standing at an empty taxi rank myself at night. I have never given him a reason to distrust me. I have never cheated and never had any dodgy messaging with anyone. My relationship with DH isn't always perfect but I thought we were happy.
This weird distrust is a new thing. I can't remember reactions like this for him before. Aibu to put this down to him being fake angry due to his own guilt about his behaviour? And what are my next steps? He will never, ever admit to anything if he has had an affair/ons.
