Worried sick

Chelsea.
So today we found out it's another girl for us so that's three :) I would have loved a boy but hay ho it's how it goes! My husband was desperate for a boy as this is our last pregnancy due to medical grounds :( I'm just so worried that in a few years he will still really want a boy and leave :( I don't know why maybe other mums feel like this but he is so disappointed in the fact it's a girl he is happy she's healthy etc and doing fine and he still kisses my stomach and stuff but he just really wanted a boy I think it's a man thing I'm just worrying maybe I'm been silly I don't know but does anyone have/had a situation like this befor?
