not sure where to go from here

[tiredndrained]

I did a little back slide yesterday. Things have been moving forward and my house is getting more stable again. Last night H went out said he was going to supermarket at 8PM. Didn't come home til 3AM. I can only take this so many times doing the 180s and not asking where he is before it stresses me out. I am not sure I am cut out to never ask where he is all the time. It is too hard. I don't know how other people do this. Got in an argument this morning. I told him I know he has one foot out the door and I can't take it anymore. Started a big argument. I left for work and that is where we left off. I know I shouldn't have said anything especially since things are getting so much better. How do other people do this? How long do I live with someone that doesn't have to be accountable for what he does yet lives in my home?
