Dear Prudence,
I’ve been in a long-term relationship with someone who has historically been polyamorous. She gave that up for me, and things have gone mostly well for about four years.
She has generally expressed that she would still prefer poly or another ethical nonmonogamy setup, and recently I have heard it more often. She even tries to encourage me to go hit on or sleep with others—which I do not want to do. I am somewhere close to demisexual, generally lean monogamous, and am not interested in seeing other people.
I don’t want to force her to be monogamous, but I also know that I do not want an open relationship and would struggle with it—especially if it were de facto one-sided. What is your advice on working through this? We still love each other very much, I just worry that disparate needs will cause our relationship to deteriorate, and I hope to get ahead of that.
