WHAT TO DO

So i have a 1yr old. Me and his dad are together. He says he loves me. The thing is its not mutual. I sometimes feel as though im with him for my son. Im not that attracted to him anymore. There are times when he just makes me feel grossed out. Like his feet! OMFG i just want to throw up. He bi**h*s like a f*g*t about nothing. I try to make things work b/c im afraid if i leave him he wont help take care of HIS son. Theres more but not enough time to type lol. What should i do
