I'm male, 34. I really wanted to have a child with my AW too. I partly thought the might stop drinking if she got pregnant. I knew then it wouldn't work, but i thought it was worth trying, and the talked me into it.
Now iI am so glad that it never happened. I see the way she treats her own daughter, she just passes her off on her parents or me. Never taking responsibley for her own child. As long as she will let me I will stay in my step daughters life, my father was an alcoholic too, and it is terrible for the children. I'm just beginning to see it now, again.
