Don’t want to be with my boyfriend anymore..

So let’s start, I’m 28 weeks pregnant with his child, have one other child(not his). Obviously I’m hormonal and some things I say aren’t entirely true but for the past month or so I’ve just not wanted to be with him, we argue a lot and recently had a massive argument, I told him to leave me to calm down and he didn’t, punched a hole in my bedroom door and then when I told him to get out he threatened to kill himself and walked out of the door, only to come back moments later like ‘what do you mean maybe we shouldn’t have gotten together’ cried, told me he would go to the doctors for his depression/ anxiety- phoned them once and hasn’t bothered since, despite me asking him to. He guilts me into doing sexual things, even though I’ve already told him I don’t want to, he makes out that I’m seeing someone else or I’m not attracted to him anymore🙄😩 he told me he would change and do things I’ve asked him to but it’s getting to a point now where I just want to leave, he hasn’t gone to the dentist for his rotten tooth so I really hate kissing him because of his bad breath, he doesn’t put his dirty clothes in the basket, or wash up, wash the clothes or anything, it’s literally me doing anything and everything🙄😔 I’m so fed up, what can I do if he doesn’t or won’t help himself? He’s pushing me away without even realising..
