I ended a 6 year relationship a month after I got sober. He was a trigger and very toxic as well. I was lucky to have my family who took care of the moving, changing of phone number and bank accounts, etc. I hope you have someone in your life to do that for you as well. Early sobriety makes us very fragile and it is helpful to have someone who cares for you and is able to take complete care of everything that you can't do for yourself.
I have to admit that I went back to him after about 6 months of sobriety. I was really missing having that partner in crime to do things with. We tried for about a month and I realized that I missed having that partner but I didn't miss having him in my life. My friends weren't excited that I went back to him but I felt that I had to do it to make sure it wasn't him that I wanted.
Good luck!! It seems that there are more of us in this situation than I thought. If you ever need to talk, you know where to find me.
