Ready to run away after 10years!

SO and I have been together almost 10 years we have 2 kids a son who is almost 9 and a daughter who is 18 months. I feel very unappreciated i have been working to support us he medically needs help i don't feel like he could do a physical labor job but i said i would do it in the mean time the family home life has went down the toilet. The housework and dinners are lacking our son is not doing his school work didn't want to help with chores or anything he has gained a very bad attitude. SO claims that he doesn't get any consideration and intamacy from me so he doesn't wanna do anything for me. I feel like I'm living in a nut house yelling and bickering all the time between him and his son and then him and me. I'm really ready to just call it quits and do it completely on my own. I've just started letting him use my car to drive for uber so he can contribute something bit he can only drive late nights because he is the stay at home parent. He claims i just wanna get rid of him for someone else which is not the case i just can't stand the craziness any longer.

Lost and going insane!!
