Solo, My 'H' is now gone (thank GOD!) I am really clear that the death of our relaationship was his abusive treatment of me.
I disengaged and that in itself became something for him to hang his Blaming Hat on.
If my 'H' finds a way to blame me for the abuse he meted out, then your STBX will easily be able to shift some of the blame and guilt for the affair and the state of play onto you...BUT ONLY IF YOU LET HIM.
Stay sharp, be on your guard and tuned into all attempts for him to bring out the violins and whine about the petrol it costs to go to and fro to see the DC.. Boo hoo
Oh I wish I was there for them, I'm worried about you... All that is bollocks, designed to blame shift so that he feels better.
Sorry to be crass, but if he really meant any of it, he wouldn't have got his dick out then would he, and nor would he CONTINUE TO DO SO?
Tell him that the next time he tries to evoke sympathy.
Call him out, every single time, don't let him off a single hook. Only when he knows that every time he opens that useless flap of skin where a mouth ought to be to say a pile of shite, he may finally stop and think.
years ago 'H' used to torture me about stuff, for hours, days, for weeks. Ex BF, friends, and life before him. I used to apologise
for it all and he used to ask What Bank can I cash your Sorry's in?
Imagine my pleasure in managing to regurgitate pretty much all the shitty snipes he used against me, years later, back to him.. The difference was, I had done nothing to him to have to apologise for, he really DID hit me, abuse me, swear at me, gaslight me, hurt me, betray me, belittle and humiliate me.
In the end I could stop him talking bollocks after about 3 or 4 words.. all of it using the stuff he used to control, manipulate and abuse me with all those years.
