First of all, I am so sorry that this has happened - a difficult pregnancy and labour, and then all this, just when you need your husband's help and support the most.
It's impossible to generalise - especially without knowing either you or your husband, but I offer some thoughts, and my 'on-line' support during this difficult time.
First of all, having a baby is a momentous experience for any nam, and because of the way we are raised - perhaps even more so in your husband's culture - the notion of talking about how excited, and seriously frightened you are by the changes and new responsibilities, is something a lot of men feel unable to share.
This will have been compounded by the fear of loosing you both during the birth, and the massive adjustment he has had to make to your new role, as well as his. A lot of men take to this change badly - mainly because they feel unable to adjust, and have no-one to talk over their fears with.
I don't think your husband is 'put off' you by events - although his behaviour would indicate that - I think he is just overwhelmed by the massive changes in you, and him, and your baby, who is suddenly no longer a nebulous concept, but a living person who needs his support and love at a time when he least able to give them.
The reaction is often to simply walk away, as he has done, but give him time, and make sure you keep all lines of communication open, and he will probably begin to get used to the new situation, and his role in it - and return to you,
There are plenty of supportive people on here who will help you through this - keep in touch with us.
Thinking of you.
