My husband of 3 years has an older sister who is a lesbian and in a relationship, there’s nothing wrong with that, however recently her girlfriend has become increasingly insistent on using my husbabds sperm so that she can get pregnant with his child, her reasoning is that she wants it to be part of her and her girlfriend, however when she told me this she never mentioned her girlfriend she only mentioned my husband and his sperm and how beautiful their baby would look. Me and my husband have both said that we don’t want that and have made it very clear. however she is still prying on about it trying to get us to ease up, I asked if his sister would want to get pregnant with the girlfriends brother, his sister said no because she doesn’t want to be fat.

A few weeks ago I started to notice that the girlfriend had started to follow my husband around like a lost puppy and started to act like his wife?? This has made me and him incredibly uncomfortable.

Should I just convince him to donate the sperm so she leaves us alone?
