I remember your story from before and just to say he’s making this difficult by being an arse post affair and not being transparent, but here’s how to heal. It takes about 3 years or so, for full healing.
You have to stop feeling like a victim of it all and that he did this to you or because he does not care about you. He did it because he’s a selfish undeveloped man child that can not take responsibility or life seriously and is full of shit my dear. That much is clear.
So stop feeling screwed over this. Every month longer in this is not so bad. You have a nice place to live, start living for God’s sake, don’t stop your vision and your life just because someone has temporarily shat on in it. Don’t allow it.
Each month longer you get more pension, your kid gets to finish their schooling in peace, you are doing this for yourself as much as them as you are currently perhaps too fragile to venture out. And when DD leaves to Uni you can then pick up and think of what you want you will be less traumatised. Then if you leave in a few yrs when u r stringer it’s fine too, he’ll have to share 2.5 yrs plus this yr DD is home extra pension assets etc and then who’s scamming who? Maybe it was yr plan to milk it and ensure his relationship fizzles out so he’s got nothing left. Seriously it’s psychopathic but gets you to stop feeling like a victim. That’s where u need to be. To feel that you could be just as ruthless rather than feel he’s put you through this. Once you get this mentality then:
Say you are sick of the betrayal and what a waste of time it has been for you and how you are moving on. Be vague about latter.
Then say if we are to move on I need complete reassurance and transparency. That means complete overview of income expenditure and comms otherwise you don’t want to be with someone who’s vague and doesn’t know what they want. It’s either real or it’s not, and you have options choices and deserve transparency or it’s off. That includes declaring any comms whatsoever from her or anything relating to that part of history. You are the only one h h st can give him family and you’re also fine to call it a day if he’s fucking with you.
Wishing you balls and strength.
