Hi and welcome.
I'm in the same position as 4ever and couldn't have put it better myself. You have to find your own way of dealing with this situation. Just be aware it is very very tough. The resentment can be overwhelming at times. Someone on here told me once (I asked almost the same question) that I needed to learn to live around him and that is exactly what I'm doing. I wish it wasn't so, but I have to do what is best for me and my recovery. Some people may say that I shouldn't and I should leave because sobriety is more important and there should be nothing left standing in the way. Well for some it might work, but for some life is just not that cut and dry. Like I said you need to find your way and just by being on SR, you made a good start. Even though at times I live around him, I'm never alone because of SR. My sobriety is a different part of my life. My husband is another. So far so good.
