my baby girl will be born next Tuesday via C-section. is it weird or bad that my main worry is that my fiance will end up leaving me?? I feel like this isn't what he wanted (his mom put into my head that even if he's unhappy with me he will only stay for the baby) I don't know what to do. I feel like if I keep bringing it up he will leave... ugh :(
