My husband's sister came to stay with us. She was distant and kept to herself. After several days I decided to go talk to her. She broke down, told me she thought she was a lesbian and she had her heart broken.

Comforting her she opened up to me and she touched a part of me that had been suppressed for many years. I am not proud of losing my self control, of cheating on my husband with his baby sister, of putting my life and home on the line. My husband forgives us but everything has changed. My feelings for his sister are raw and overwhelming. I am dealing again with my feelings. She is his sister, that is why I am in love with her, they may be male and female but they are so alike. Still no excuse I am in love with her and I want to stay married too. If I wasn't with his sister I am pretty sure my marriage would be over by now.
