Just caught your updates and saw that H is in contact with DD daily, and I must say, that even IF this was the most innocent trip ever, he certainly actioned it in the most suspicious way possible. Even IF there’s no OW, MH crisis or dodgy financial/business dealings, why oh why couldn’t he have been more open and more transparent with you before he left?
THAT, imo is the problem here and the reason you’ve apparently been so accusatory and “ruined his vacation” 🙄
If nothing else, it highlights the fact that he’s been treating you poorly for some time, and also keeping you in the dark about certain (important) things for a huge portion of your marriage to him.
OW or not, it’s clear he thinks it’s ok to treat you this way - and I think we’re all in agreement that he’s very much mistaken there. Don’t let him (and dd) gaslight you into thinking this is your problem, your overreaction, your paranoia etc. He’s a nasty bastard, plain and simple, and you are well within your rights to finally stand up to him about it. He’s acted horribly. This holiday should absolutely be the final chance he has to treat you like a mug.
Sending hugs and strength to you, OP - you seem to be holding it down, and maintaining your composure…you should be proud of how you’ve dealt with this tbh. Strong, dignified, no-BS… I like your style! He’s coming home to a big surprise when he recognises you aren’t going to let him walk over you any longer. Good for you, girl! 🙌🏼💗🏆💪🏼
