My DH’s best friend B (50s, professionally successful) ended his marriage by having a long affair with his wife’s close friend. He caused a lot of hurt to his wife and children to whom we remain close. My DH has stayed friends with B throughout and continued to see him alone/in other male company. I have not really seen him and he knows that I disapprove of how he ended his marriage.
The affair has now ended and B is leading a single life in London. He now invites my DH to parties and dinners without me (even when everyone else’s partner is invited). The next one is 3 couples plus DH and a single woman. I don’t like that – I think it disrespects our marriage, it leaves me at home doing domestics while DH is out having fun (this already happens quite a lot as I have a demanding job and do the lion share of household/kids for various reasons) and echoes how B treated his own wife. DH can’t see the problem. He says I wouldn’t want to go myself – which is true (as I feel uncomfortable around B due to all the lies/deceit that went with his affair). DH would also (reluctantly) cancel if I make him (and would tell B that is why). But for himself, he thinks it is fine for me not to be asked and for him to accept and go alone. AIBU in being hurt by DH’s view?
