My fiancé of 7y thinks she is lesbian. She feels going through relationships she may have suppressed these feelings and after talking to a friend who is lesbian it’s made her question her feelings more. We have a 6m son, a house & planning a wedding, I’m devastated. I love her but I don’t want her to hide her feelings and they possibly reoccur at a later stage. I want what’s best for us but also our son. Any advice please?
