theguardian: Five years ago, I went through a bi phase and used to sleep around with pretty much everyone that came along.
This changed when I fell in love with my new partner, who is everything to me. I recently met her parents and halfway through lunch realised that I had slept with her father. I was going to propose, but when my partner and her mother were away, he told me to end it with his daughter. I’m obviously in love – shall I just ignore him, or tell my partner?
I am not sure you could ever have a comfortable future with your new partner. To tell the truth would be to court disaster: a probable break-up, plus the risk of a permanent rift between father and daughter and father and wife. Hiding the truth would lead to toxic secret-keeping that could be equally destructive in the long run.
If this whole family was as open-minded and sexually open as you, it might be possible for you to become part of it. However, the father – your former lover – has made it clear that you will not be welcome. Walk away now, and avoid the massive pain that would otherwise be inflicted on your partner, her family and yourself.
