Lupins-I dont mean this to sound patronising or scary but...dons 'trained counsellor' hat (I really am, got certificate and everything-mind you they do practically give them away), I think maybe he needs to get some help.It sounds to me as if this might be about issues other than the pregnancy but the baby has bought it all to the fore..
Could he be suffering from depression do you think? And have been doing so for a while?
His reaction to your news about having a boy isnt what you might expect and having a boy is a seperate issue from worrying about money..Boys and girls cost the same..It sounds to me as if he is off loading it all in one big lump and focussing all his unhappiness on that issue rather than the fact that he might be unhappy in himself..However I must iterate his unhappiness (general or regarding baby) is NOT your fault..please dont for a second think it is or feel guilty about anything at all(easier said than done of course).Furthermore you can help him deal with it, but its a journey he has to undertake largely on his own, (to sound sappy, apologies).I would really try to get him to go see his GP if he will and get a referral for some counselling..I think this is important, for him, but also for you..Your focus right now has to be your lo's.
If you speak to him later and its all resolved re the baby and he apologies and all I would still try to get him to go and speak to someone because it sounds like there might be things going on with him..(obviously having never met him thts not a qualified opinion but..)
Anyone can get depressed at any time and sometimes nothing seems to cause it..its often a chemical thing..to attribute it to one cause, in this case the baby isnt normally speaking very valid...
I wish I could give you a proper cuddle..
O SOH, I was exactly the same as you when I found dd 1 wasnt the boy id imagined all along, (found out before she was born fortunately).Made me not want to be pg at the time, think it wouldnt be how I wanted it and that I would be a terrible Mum because she was a girl and I wanted a boy.As soon as she arrived all that went away and I love that girl more than anything..this one is a girl as well and I havent been so bothered this time around, but I still yearn for my boy sometimes if im being totally honest..though I think when baby arrives I wont feel like that...
