I don't quite know what to do.
Married XH 2007, DC12 b.2010, DC10 b. 2011, separated 2017, divorced 2019.
New partner, new baby, all good / balanced / happy in the main.
XH shows tendencies towards narcissistic personality disorder, sociopathic behaviour - I'm no expert but I've listened to HG Tudor, read Lundy Bancroft, and noted XFIL shared similar characteristics. XH enjoys being cruel, to people and animals (to make himself feel better / superior), puts people down in front of others / mocks, bullies, never admits he's wrong, has an attitude / arrogance about him which reeks of superiority, smirks when others fail / when you are upset by something he's done, even his walk is haughty and dismissive. It was hateful living with him and being mocked, denigrated, made to feel inferior, derided, lied to, just generally made to feel like I had no business being on this planet. He took all of my self worth away from me and made me totally numb, unfeeling. Hollow.
So on to my AIBU. I don't know what to do. Down to the way he speaks, looks, walks, behaves, smirks, even the way he bloody EATS, his manner, the way he - if I'm spelling out how a game is played, or how to load the dishwasher or cook an egg for for example - just does not listen, so when it's his turn he doesn't know what he's doing, the way he behaves towards me if I'm telling him off, the terrible way he speaks to his younger brother. My DC12 is the absolute spit of his dad.
I am so triggered and I don't know what to do with myself. All the traits and characteristics which I absolutely hated and resented and which made me totally mad, are in my DC12.
I know he has other more positive aspects to him - he has (some) empathy, compassion, he is loving and he cares. He's learnt all this by rote, and I think he probably has inherited some of these rather more emotionally intelligent parts of his character from me / other family members / my partner, but I just don't know what to do about how he makes me feel, all too often.
Please help.
