A few of my recovery friends have either lived or are living in a sober facility. They love it. They feel safe, they appreciate the accountability it requires and they have a counselor there 24/7 to talk to if they need a steady hand.
I guess I really don't understand what your boyfriend is upset about? Are you saying he sells drugs to the women in the sober house and that your being there will interfere with that? It all sounds confusing, and selfish, to me.
Regardless of whether you go to sober living or find a place of your own, please focus on yourself. You can get a dog a year down the road when you've got some sobriety on your side and some money in your pockets.
