It is shared news and if he wants to tell people about his impending fatherhood that's totally up to him.
It would make him a twat, as I said.
Yes - his baby too.
No - not his pregnancy too.
Not his place to tell anyone the pregnant woman doesn't want knowing.
Fair?
No. Biology isn't!
Her pregnancy. Up to her who she has with her, how she births, who she tells her personal medical details to.
Not his pregnancy. No stretch marks, potential birth trauma, fight back to physical fitness, nights of no sleep while feeding. That's alllll on her, whoopee! (what was that about sharing again-?!) Also - get this - he's also free to decide in Week 34 that he's changed his mind and walk out that very day if he so chooses.
No, biology isn't fair. When it comes to pregnancy, the least a decent man and impending father can do is respect the partner who has to go through it.
