I feel a little sad about this too; nearly 20 years wasted on a man who appears great on the surface - chatty, friendly, affable "Mr Nice Guy". Well, for the first 2 years of the relationship, until I had moved in, away from family & friends. I didn't see the red flags, my boundaries were crap. With hindsight, he targeted me & I didn't protect myself enough.
Then the shittiness began & the mask began to slip. The real person underneath was incredibly selfish, prioritised their career & hobbies over family life, did sod all round the house.
He hadn't been honest about his mental health issues, couldn't hold down a job & was disengaged, angry & we walked on eggshells.
We had 2 young kids I was working part-time, juggling the house & trying to hold it all together. As woman we are socialised to sacrifice ourselves & "fix it".
Eventually I had enough.
He has been far worse than I could ever have anticipated. He's another one who made false allegations about me (I self-reported to protect myself as am a HCP). He called the police on me & threatened legal action when I went to stay with my parents with the DC. Refused the sell the house. Forced me to live with him for 18m afterwards and subjected us all to hell.
There's a few things that have helped me: counselling, the Lundy Bancroft book, and "Psychopath Free" - the latter of which details toxic behaviour.
I'm still battling to get the house sold, to be ultimately free of him (well, as much as you can do with 2 children). I want to reclaim my life & be happy without him hindering it.
