Husband called me a fucking pig

Just a little bit ago, we were laying down to go to bed. I had to fart, so i did and he got mad saying i did that on purpose and that i should have turned the other way and called me a fucking pig. Hes being so nasty to me and i dont know what i did to deserve this treatment. I do all the cooking and cleaning, i work full time and care for our daughter when im home so he doesnt have to. He literally does nothing because his foot and knee hurt all the time (medical issues).

This last monday he got mad at me because he couldnt find his jeans when he was going to the hospital for ketoacidosis (because he never follows a fucking diabetic diet!!!) and said that i must have hid them from him. He got so mad that he was talking about going to his moms for 2 weeks. Honestly, i wish he would have gone. I want him gone if he doesnt start treating me better. We dont even have sex anymore. He doesn't even look at me like that. Im sure hes on tindr or bumble, but im too scared to actually look. Hes been on there before talking to other women, and like a moron, i forgave him. I try to forget about it, but with as often as he ignores me, im sure hes watching porn whenever he can and talking to other women online. I even caught him sending dick pics on snapchat before.
