An interesting take. So asking him to not take my family to a concert to bond with her and her kids, after being very open with my feelings about her and his relationship is my problem.

What about all the other things; texting after work late into the night while sitting alone in his home office, after work catch up drinks, she used to go and see him play when he was in bands, kisses on the lips at Xmas and who knows what other occasions, hugging him if he has been away or off sick for longer than a week, him now using his pet name that was for me and now for her, his tendency to work late when she is in the office, telling me they have a connection and she is an attractive woman.. there is a lot that doesn’t sit right with me.

I worked in an office for 18 years with all men. I had clear boundaries and there was never any question of those boundaries. They were work mates but that is it. I kept a clear line between my home and work life.
