What will u do if u know the day of ur marriage that ur fiance is infertile ?

This kind of happenned to me but not exactly as youre saying, but I had a miscarriage less than 2 months after we married and then got pregnant again, and miscarried again within 2 months, and then in the next 2 years got pregnant 2 more times but lost both babies. Finally my doctor said to stop trying because it was ruining my emotionally, and they coudln't find anything wrong. My husband chose to stay married to me, for now, but it's scary.

Well it wouldn't exactly be the best day to leave it to tell someone! I think it would change things to some extent, but at the end of the day you can't choose who you love!
