I have been in a literal living hell with my husband ever since we got married. He is currently in jail for hitting me because I didn't want him to get high and I was trying to leave. We have two very small children and I have this illusion in my head of us being a happy family one day, every time he is in rehab or jail he promises the world to me and says he will stay sober but this never happens. I love him and I don't know what to do, so my question is can a drug addict actually change? or am I wasting my life thinking he ever will change?
