I feel like my marriage is falling apart

There has been a lot going on with me. Some stuff I rather not get into.

My husband makes me feel unwanted, unloved, under appropriate and I’m sure it goes both way. We have separated before and we worked things out or so I thought. We don’t have sex because he doesn’t like it and I like sex but I don’t get it. I don’t care about sex as long as I still feel wanted. Don’t get me wrong I want sex and whatnot but it’s not everything. Here lately me and my husband has been fighting a lot about things and each time I try to bring up how I feel he shits me down or gets pissed at me or he “says I’m just a bad husband my bad.” I don’t feel like I can talk to him about this stuff anymore. He always tells me he will try to make things better and they are good for a a few days and then it’s right back to the disappointment and idk if I can keep this up for much longer. I’m scared to say anything to him because I know it will lead to a fight or nothing changing after he promises. But I’m unhappy and I don’t like he is happy even tho he says he is. Idk what to do
