Hi OP, sorry to hear you have had a shit time. I am only realising the depth of the hurt and pain an EA relationship has had on me two years out. Now I am getting more serious in a new relationship its thrown up a lot of insecurities.
When we were first dating (I was 17, together for 21 years), I didn't really notice it. Although from very early on I realised he had bad moods and was what I now see as controlling (then I just thought he was crazy mad about me). I should have left him once we first moved in together and I caught him kissing a mututal friend. I didnt. I stayed. Then I fell pregnant, lost the baby. Decided all I wanted to be was a mum, so the next few years I felt the relationship was ok. It wasnt really.
Things he always did: never acknowledged if I needed either emotional of physical support. When I had my MC he didnt come to any appointments or the hospital with me (I need a D&C 6 weeks later). He would shout at me if I asked him for help. He would always comment on what I was wearing. Little things like "are you wearing those shoes with that" or "did you buy that dress/top when you were with your mum". Snidy digs a lot of the time, chipping away at my self esteeem. I always felt like he felt he was doing me a favour, even related to the kids. We did have fun and during this time I do believe I loved him. But I longed for a more loving supportive relationship, and the moods did affect me. I used to run around at 4pm to get the house straight as he'd be back at 5 and asking me what I had done all day (I used to work 13 hour shifts so had some days off in the week).
We moved abroad about 7 years ago with two kids under 4. He decided that depsite it not being the plan he would "retire" he left me to find the work, which I did. It was a good job which involved travel. He had to pick up more of the childcare, although as soon as I was not at work, he handed all that back to me. We live in a beautiful place, its like paradise. He still wasn't happy. Too lazy to get a job, too fed up to enjoy being at home. The emtional abuse worsened, it was daily. The fun times were peppered with anger, abuse etc. He would forget about it as soon as it came out of his mouth.
In the final year before i left, he screamed and called me a cunt in front of the kids as I dared to ak if I could go to the gym on a weekend. The gym was my only escape. He spat in my face. One drunken night he put his hands round my throat. Once I realised that the kids were picking up on his behavoiur and it was and would affect them for the rest of their lives I decided I had to leave. This and many many more things and I still felt maybe it "wasnt that bad". You see we are conditioned to it. Conditioned to forget about it after it happened, in the earlier years I would always be the one to apologise, just to smooth things over and try get on with our lives. He rarely if ever apologised. He felt entitled to be able to behave how ever he wanted.
He still tries to emotionally manipulate me, and he still can push my buttons. I cannot believe I was with him for so long and missed so many "red flags" in the early days. I wish mumsnet had been around then, it was posting on here that gave me the realisation I needed.
I am still broken by it, I have what I think is adrenal fatigue, but I am 100% happier now I have my freedom and not having every move scrutinised. One of the final straws for me was him standing over me telling me how to cook pizza. And then instructing me to be careful with the crumbs as he had only "cleaned this fucking house 2 hours ago". He has what I realise now, aside from just being a bully he also has OCD and anxiety (and an alcohol dependency). Its a perfect shit storm. He never expected I would leave him, not in a million years. The fall out since has been hard. I thought we might be able to be friends as when he wasnt being abusive, we got on well, similar interests, sense of humour etc. No way that will happen.
The hardest thing for me to deal with was my perceived guilt, I am a people pleaser and unfortunately always put my needs last. That is changing now, I realise I am just as important as anyone else but its taken a long long time. My eldest son can see him for what he is, my youngest seems a bit oblivious by it all. On the whole since I left they dont see the shit I get, and I am very proud of us all. They are wonderfully kind and caring boys and both very emotionally mature. If I had stayed, that might not be the case. In a way I left for them, I could not be party to them growing up like that and he sure as shit wasn't going to change. I feel pity for him now as he will end up a very lonely man. I believe he has probably got an undiagnosed personality disorder, and he needs serious help if he will ever be happy in the future. Sometimes I think he likes being miserable and sucking the joy out of everything.
