My ex and I separated last year. We had been together over a decade and had 2 DCs.
I left because he was emotionally and financially abusive. But recently I have been thinking about our sex life and I feel quite uncomfortable about some aspects of it.
Forgive me if I'm not explaining myself well but I'm trying to get it straight in my head.
He would often comment on my body in a way I found embarrassing. He would call my breasts 'boobie-woobies' and jiggle them. I hated this and told him. He would then get very offended and I would end up apologising for my 'insensitivity'. The next time I undressed he would make similar comments.
One of our DCs had serious sleep issues. He never helped at night and I was exhausted. He would regularly complain about the fact we weren't having much sex. Consequently, I often had sex with him when I didn't want to because I felt guilty about his frustration and because he would sulk if it had been too long. Sometimes I got into it but I mostly just endured it. I remember lying there crying silently on more than one occasion. He didn't notice because it was dark. On numerous other occasions I let him continue even though he was hurting me. I didn't ask him to stop because I knew he would sulk and it was easier just to let him finish.
This isn't normal is it? 
I don't know how to process this. I can't work out if it was abusive or just symptomatic of our generally toxic relationship.
My ex and I were together for 15 years and he's the only man I've ever had sex with so I have nothing to compare this to.
