OP, do you have anyone you could talk to about this in real life? I think it could help. Or even book a counsellor for some impartial support. It’s probably about £60 per session, but so what - it’s nothing to what he’s spent on women, is it? You could have 12 sessions for the money he’s wasted.
What he is doing now is biding his time as he reckons you will “get over it” in a few days or weeks. He probably thinks, “Oh it’s Christmas soon, I’ll just have to get her a nicer-than-usual present and that’ll shut her up and we can all move on to the New Year... new start for “us” etc etc - all that bollocks...”
OP, I don’t know you obviously. But I am 47 and know a lot of people and I can honestly say to you that I can’t think of a single woman who would stay with a man like this. Not one.
I’m not telling you they to make you feel any worse because you don’t need that. I’m telling you because it’s the truth. You shouldn’t have to contend with this kind of thing and you deserve so much better then a man like this. It’s truly appalling.
I haven’t posted in AIBU for ages but felt compelled to on your behalf because this man sounds hideous and an utter hypocrite.
Please confide in someone on real life and don’t let him wear you down until there’s nothing left. You sound intelligent and lovely, but he will drain the life out of you. Take care and don’t get worn down by him. No more.
