You cannot control or influence his fuckery but you do have control over how much you let it impact your life.
He thinks (insert the idiotic rant of the week)... ? Who the fuck cares?
As I said to the sad clown shortly after S "What you think of me matters less to me than you might imagine."
Practice this. I suspect you don't really give a flying fuck what he thinks but for the drama it causes. You can control that y'know. Just ice him out.
You didn't abandon him - these are the consequences of his actions and choices. He's upset because you wouldn't let him cake eat. Boo fucking hoo.
He does it about the house now but when that is no longer an opportunity he'll find other ways to torment you. That's why it is so important to a) reduce the opportunities he gets to launch grenades; and b) develop skills to become impervious to the grenades they do get to launch.
I personally don't understand the venom either. The best I can figure out is they do it as a reaction to losing their perceived control over us. They can't get positive attention from us so go for the next best thing, negative attention.
You see the same behaviour in toddlers before they learn how to process and express their emotions. These guys are no different. Arrested development that existed long before we entered the picture and is one of the factors that led them to cheat in the first place.
Ironic that they seem to have this insatiable need for our attention now - what I would have done to have him want my attention in the dying years of our M!! I got zip, zilch, nada. Because he still had control of me back then.
Now I have neither want or need of his attention anymore. I would rather set my hair alight. Because I am healing and growing. I am truly moving on in heart, mind and spirit.
He on the other hand has pretended to move on with his latest victim but his mind is still stuck in Xanadu where he felt like a king.
Too bad motherfucker. The king is dead - long live the Queen!!
I do wish his life was fulfilling enough for him to not seek my attention. I pity him that. That must suuuuuuck - especially given how easily he cast me aside. Sellers remorse.
In his destructive and devastating quest for freedom I have ended up the one who was set free. Who knew eh?
