Dh went off the rails??

[ICanSeeForMiles]

Having a chat tonight, background, dh is self employed, I am sahm.
Long story short, I brought up having another baby at some time. We currently have two dc, 7 and 4 and I am planning on going back to work this year when youngest at school. So I brought up the possibility of having another dc at some point in the future. Dh goes mental, I know he's self employed, has a hard working day, I don't deny that. However I just brought it up, now he's in the spare room having gone bonkers. WTF???????

Tempus I think I've gotten to the bottom of it. He is one of 4 children and he says himself they weren't well off at all. He's said that he would much rather be able to give the two children we do have a better standard of living, holidays etc without stretching ourselves too thin with another child. Now see if he'd just said this last night I would have completely understood and agreed.
Now, any tips on getting rid of broodiness??

It goes, you just ride it out.
