Dear Prudence,
My boyfriend and I have been together for four years now. We’ve never had any major relationship problems, have always been good at dealing with conflict, and have been considering getting married in the relatively near future. A few nights ago, he was talking about his family history, and a bomb dropped on everything.
It turns out we must be fourth or fifth cousins. This has honestly disconcerted both of us, but me more than him. I still love him, but I don’t think I can ever look at him in the same way again. I’m not sure if I want to go through with the marriage anymore. Please help, this has been the healthiest and happiest relationship of my life, but I can’t say I feel comfortable with it knowing I’m related to him, however distantly.
—Does It Count as Incest If We Didn’t Know?
