Is IVF a curse in disguise?

1. I donated my sperm to a couple about two years ago and everything has changed in my life. I feel guilty because I think I partly contributed to a divorce. After the baby was born, the husband claimed he was disrespected on a daily basis by his wife and they divorced a week ago. However, that’s not the twisted part, the wife wants me to be her new husband. We had decided to keep the lines open for a year but it seems like varnishing was the better option. Now I have a baby with my genes, an angry husband, and a woman I barely know who wants ne to marry her. Is IVF a curse in disguise?
