Mother help..

My husband is an alcoholic. I finally got him to agree to go to counseling and his first session with the therapist is on Monday. Last Tuesday I found him sexting a girl. I feel so betrayed and disgusted with my life. I was ready to leave, met with a lawyer, told his whole family, but after seeing him when he sobered up he legitimately looked like he hates himself. I don’t forgive him for any of this at all, but I want to try and get him help. My mom watches our son for us and she is threatening to move back home (another state) because she doesn’t want to watch him continue to do this. I’m so stuck. He’s still my husband, we have a son together, and I am pregnant with our daughter. I feel traumatized from all of it. He agreed to let me monitor his bank, phone, all of it. Clear transparency. He asked if he could drink last night and I caved, but he actually controlled him self. He did every thing I asked and for up with our son last night. Yet I feel stupid for being here because I know I would tell my friends to leave if they were in this situation.

I kind of rambled on.. but has anyone been in a situation like this? Did counseling help? Did your friends and family forgive you for staying?
