I am quite good friends with a man that I work with. We've worked together for around 10 years and have spent many lunchtimes alone together at a local cafe as well as group nights out and a few evening trips to the pub after work here and there, sometimes alone and sometimes with a group. Nothing sexual has ever happened, not even after alcohol! We are just friends and enjoy each other's company. We are both married with children.
The problem is with his wife. I have met her a handful of times at work but he's never admitted to her that we have a friendship. When I meet her I have to pretend he and I are not close. She's very jealous and insecure and wouldn't like it, even though it really is just a friendship and she has absolutely nothing to worry about.
It's not just about me either. I have asked him and she's jealous of a lot of women, often accuses him of cheating/having affairs, will sulk and not speak to him if he mentions some of women that we work with. Lately I've felt really sorry for him due to some of her behaviours and accusations.
Do you think this is a form of abuse? He does still have the freedom to go out, she doesn't stop him, however, she can become sulky about it and sometimes will try to make him feel guilty about going out. He also has to lie to his wife about who he is with if there are women in the party, he has to delete any text messages that I send him straight away (I assume this is the case with other women he might text too), he can't have female friends visit the house. Is this normal? Is it acceptable behaviour? Should I try to speak to him about this?
