OP if you knew it was in his "culture" to do this (i'm not even going to go there) and you weren't happy about his attitude on it- why are you having his baby in the first place? Please forgive me for being brash- but I can only assume this baby wasn't part of your plan together.
If it was- i'm sorry, but if you knew he would be like this and you still chose to have a baby together then I can't find much sympathy for you.
Different kettle of fish however if it was a mutual decision and he said he would support you.
Either way I think you have to question whether or not you really want to be with him.
