Should I feel sorry for my children’s father?

So my children’s dad has been battling with addiction for years, he’s not addicted to crack & it’s caused significant problems in our relationship, from stealing money from me & kids to being mentally abusive, throwing me & the children out of our own home, to being asked to leave a rehabilitation center for smoking cannabis, I’ve put up so many walls now with him sadly and we haven’t slept together in a long time, he keeps telling me that if he had more affection his addiction wouldn’t be so bad, I tired to hug him earlier as he looked somewhat depressed & he said there’s no point as it will come to nighttime & it will be the exact same, (he is insinuating sex) I don’t want to be sexually active with him until I actually see him making some kind of effort but unfortunately in his mind he won’t get better until I show more “affection” me and the children are going to have our own home soon but i just feel so deflated with the whole situation. He never understands it from my point of view and how decremental this has been on our relationship. And he makes me pity him sometimes, and even to the point of leaving, he makes me feel bad, can anyone help here?

I don’t think it’s romantic …. I feel suffocated and pressured for sex
