My husband also in the 'no' camp, think actually he couldn't go through it all again if you know what I mean, he supported my decision but was really sad when it all happened. Talking about gtting the snip, making it all seem so final, which makes it worse.
When I was pregnant I wrote down all the reasons not to keep and to keep, actually the practicalities outweighed having a baby, this helps as actually practicalities could in turn make life hard for all of us, (I keep telling myself this).
Lovely that your friends have been good about it as although you don't need sympathy, just a 'sorry your going through this' attitude is helpful.
I told my b friend all the way through, as I was ok about it when I found out, just as the hormones wore on....
I do think if it is meant to be it will happen... just not sure if I want something I can't have or I do actually want a third child, time will tell once the practicalities are sorted out ...
I guess concentrating on your business and life in general will help..
