Sex drive help!!

I need help, I am a mom of 3 girls. I have been with my boyfriend (kids dad) for 8 years! We are not married. I have been the bread winner for the last 5 years, feeling very used like a meal ticket with no appreciation. He even made me cut my maternity leave short so he could quit his part time job (he wasn’t happy) ( I made really good money with my job At the time) fast forward to now.. we are both working, but I feel like We’re rocky with all that we have been through. We haven’t had sex in 6 months, just the thought of him touching me is repulsive, we are basically just roommates. I don’t know what to do, I’m all alone. I don’t have friends (new city) and I don’t have family. It’s just been the 2 of us for so long, I think I hold on just because I don’t know how to function separately. It sucks because I am young, and I want true love. I want to get married one day...

I’m sorry about my long rant, just needed a place to talk.
