you need to scare him!

thats what I did with my OH. Let him know that if he isn't willing to make adjustments for this life changing event, and if you are having to do it all yourself. Then you can do it all yourself without him. I told my OH that if he wasn't willing to make some sacrifices and I was the only one sacrificing things, time, money, etc then I didn't even need him around, LO and I would be just the same without him.
Hope things work out for you though.
