Going No contact is good for the skin and overall health. I have also lost weight.
Yesterday I met a really HANDSOME coworker that is also very very kind and a GENTLEMAN. Nice guys exist and are out there and I hope you give yourself the chance to meet them and share good moments with healthier people . But you do that by getting there yourself first. Keep moving forward!!
BTW I also got a XABF, I went NC 2 years ago and guess what? he has been drinking the same way all this time and still sees no issues! (at least not for him) LOL! its not worth your time or effort and even more so when he is also taking drugs as well. That is lack of self esteem and comes from many many years ago for him, since childhood or even way before that, according to his family history etc etc... YOU, SereniTee, are not going to "fix" any of that magically.
And perhaps if he loses you it motivates him to get better.
