About 18 months ago my husband went out with work friends. He mainly works with females. No issues with this. He came home blind drunk, was shouting on the doorstep to someone who had given him a lift home. I went down to him and he was flat out on the sofa with his phone. I picked it up and he'd sent a Facebook message to a woman he works with daughter. He'd said are you ok and she replied yeah thanks. That was it. I thought it was odd so looked at his other messages on WhatsApp. They were to his female colleagues saying how stunning they looked and that he'd had a brilliant night etc. I woke him up and asked him what they were about he was so drunk I couldn't get anything out of him. The next day I asked what that was about. He just didn't seem to have an answer but said they were work colleagues and I asked about the woman's daughter. He said she works there now. I said I wasn't comfortable with it and he's said ok. He also doesn't drink when he goes out with them anymore. Fast forward to today and I was on Facebook and there was a friend I had in common with a lot of people but didn't recognize the name. I clicked on the profile and it turns out it's a colleague of my husbands. There was a post of him and the women he works with from a few months ago. I knew he'd gone out but he's tagged in this picture and it isn't on his profile so I'd have never seen it if I hadn't looked at this woman's profile. There is nothing untoward and he drove there. However, his brother has commented on the post and isn't friends with the woman. Does that mean he's hiding posts from me? I have no clue on things like this! But I don't get it as I knew he was out with them all so nothing to hide.
