I need advice please

So… i need advice or to vent. Not sure which one. Maybe both. My husband and I have been together 11 years and married for seven. We have two beautiful kids together. The least year or so he has really been disrespectful towards me( verbally and mentally abusive). He drinks a lot… He’s barely ever home and when he is he just talks down to me. Forgive me if this is too much… but he always asks for sex from me. I do do it sometimes. But even when I do it’s never enough. It’s not that I’m not attracted to my husband, because I am. I’m just not attracted to the way he treats me. I’m trying really hard to stay strong for the kids but I’m crumbling here. I’m just feeling empty I guess and I don’t know where to go from here. I asked him to go to therapy but he claims therapy doesn’t work.
