I got to this stage with my first xh, LMW.
He was selfish. If he couldn't go to the pub at night, he would go to bed straight after his dinner (about 7 o'clock) and leave me with our 2 DD's for company. He never gave me any money. If I complained, he would just stare at me and say absolutely nothing. He used to shout at the DD's when they cried as babies, because they were keeping him awake. Everything got done his way, or he was leaving us.
In the end, I hated him. I would have sex with him and cry (like you). He didn't force me into sex, but I was afraid if I didn't have it, he would leave, and I didn't want to be a single parent (don't know if this is how you feel?) I didn't want to be abandoned, but neither did I want to be with him for the rest of my life.
Once I'd got to the crying-during-sex stage, I knew it was over really. My sister said, 'stick with him. He's the father of your children. If it's only about sex, an orgasm is an orgasm, and it doesn't matter who gives it to you'. I couldn't agree less. He reminded me of a grunting pig, and I felt like some cheap slapper for having sex with a man who repulsed me.
I hope the counsellor will help you to find your way through this. It feels like a trap you can't get out of. But you can. Whether you work through it with him, or you get out, it doesn't have to remain as it is.
Wishing you all the best.
