I didn't know we are cousins!

Well here's my confession story, I would love to know ya'll thoughts.
About a year and a half into this relationship (after we fell madly in love) I found out he's like my 5th cousin. My mom told me and said we could never have children and that she knew the whole time but wasn't going to tell me. Anyway I don't care that we're cousins cause it's through marriage and we've been together now for 3 years and 8 months ❤️
