Living In Sin

I married my husband in college because I was pregnant. When he was in high school he had married a younger girl because she was pregnant. Our kids are three years apart. After I was married I found out he may not have been properly divorced. By then his ex? was out of high school. My husband? decided I should look after her son while she got a chance at college.

Fast forward to today. Yes, her marriage was not properly dissolved, technically he is a bigamist. We live as her being the ex and me being the wife. For her to go to college she moved in with us. Another two babies came along. I guess because of our age difference I am her older sister and she is my baby sister. Nobody questions that we are sisters. We live that way.
