Well if you didn't have a strong preference, then I guess you can't know how she's feeling??? Plenty of people have preferences, there's websites and forums online dedicated to gender disappointment. These people can't just switch it off, they feel bad they feel that way, but they can't help it.
It sounds to me that you're a bit offended because her preference is opposite to the sex of your child and you seem to feel like if she doesn't want a boy, it's some sort of insult to your son?
I had a slight preference for a girl because I had a wonderful relationship with my (now deceased) mum and I wanted to share that with a daughter.
My DH has a slight preference for a girl too, as he's not a typical blokey bloke and felt her would relate better to a girl.
Last week we found out we're having a boy. That's absolutely fine with us. I've been so ill in this pregnancy, that just having a healthy child at the end of it is all I want. I'm quite excited about meeting my little man.
But, being so ill, I'm really not sure I'll have another. I always wanted two children but currently don't think I could face another pregnancy. So this son might be it for us.
I caught sight of my old dolls house yesterday, which I had been keeping to hand down to a daughter. It hit me that I may never have a daughter to give it too, and that made me sad. It doesn't make my son any less wanted
It sounds like your friend is scared of being disappointed if she has a son. She's probably being sensible by not finding out, as she knows she'll love her baby regardless when she first sees it. Cut her some slack OP, she's hardly being a monster.
