Don't give up! Don't give him this last victory! I know you're exhausted by it, but you're in the final leg now, you can do this.
Start the legal process to get him removed, perhaps just beginning the process will get him to realize your serious about not taking his shit anymore and will get him to move out, if not it will give you a definite point when he will leave and you can just keep your head down and get through it until then. What's more, it'll give you some much needed self-respect. It'll be the point when you stopped being beaten down by his crap, and started fighting back.
I know it's exhausting, but just a little further now. You can do this. This is like transition in labour. It feels like you can't do it anymore, you're totally exhausted and feel like you can't go on, but you can, you will, and something amazing will come out of this you'll be free!
I know you just want to feel relaxed at home, but he wont let you because if he does he's lost his power to try and control you. So you need to find somewhere else you can find relaxation. Exercise at the gym? Swim? Coffee shop? Best friend's house? Mum's house? A counsellor? Send the DD's away to stay the night with a friend or family member and get a hotel room for the night if you have to. You can do this.
sending you some very un MN ((((hugs))))
