She Has No Choice To Divorce

My aunt is an unlucky woman I think. She has apart with her husband since 15 years ago. That was a hard time for her because she has to take care of the children. She has three children that age from 3 to 8 years old. My mother told me aunt loves her husband very much actually, however she has no choice to divorce because her husband have drug addiction and never think of stop the addiction. My Aunt ever found a good drug rehab for him but he does not want to attend the program. I think my aunt had given him maximum chance to save their marriage. Too bad he never realizes it.
