Please tell me - AIBU
when we got together, almost 7 years ago, my husband was super insecure. He'd come out of a bad relationship and had trust issues so struggled A LOT with my male friends and me going out by myself. I took the approach of I loved him and wanted to help him gain confidence and so reassured him a lot, went out less and was very supportive / open about my male friends (there were not many and not close friends) but gradually these fell away and gradually I stopped going out without him.
My husband recently had a birthday. He showed me a message from a female friend but it was in German (his language) and told me it was just a general catch up message with happy birthday and, because he wanted to be open, there was nothing to worry about.
I thought that was all weird (too much reassurance when it wasn't needed) so a few weeks later I google translated the messages.
He'd messaged her talking about a what if moment about when they'd nearly gone out and imagine what would have happened and did she ever think about it. She messaged back saying stuff would definitely have happened. She asked if he'd be sunbathing nude on holiday etc
For context, they are both married with kids. our marriage is not going well. We have a 4 year old and he's not exactly enjoying family life (he doesn't do a lot with him) and is often complaining my main focus is our DS. Whilst I do try to give DH attention (date nights, sex 3x p/w etc) our DS does need attention and I am pretty much the only person looking after him.
Am I right to feel annoyed with the hypocrisy and like this is the first step to cheating? I am at the moment furious and need some rationalisation I think.
Or am I being insecure and need to focus on him a bit more?
I don't mind him having female friends, but he doesn't mention me in any messages, there's no suggestion of us meeting up all together so we can be couple mates so this all feels secret and like he's a massive hypocrite.
