My first marriage was like your relationship OP,I was with him from when I was 16,I managed to get away when I was 25 and had two young children.
I won't come back to this thread after I've wrote this because what you've described is what I went through and I can't read anymore it's just to hard,sorry.
Please leave this relationship,it's abusive and it's one of the worst kinds of abusive,my ex husband was the same,I didn't get a break from it all when I was on a period.If he wanted sex,a blow job what ever he got it because it was his right as my Husband.
It took me years to realize that I'd been being raped and sexually abused by my then husband nearly every day that we'd been together.
He was the same as your partner as well,I could see other people and go out but only if he was there.
It took me along time to start to recover from what he put me through but I have healed alot,I got married to a man that is a million miles away from what my ex was like and we now have 5DC.
I had sons and I didn't want them growing up thinking what they're Dad was like was normal.
You have a daughter I'd be even more worried,leave before she grows up thinking that the way your treated is the way she'll be treated when she's an adult.
