Hey, I think everyone has given great advice, I just wanted to tell you that there is hope, so don't get too down.
When I was pregnant, DP suddenly quit his job and decided he didn't want to work at all, and he played PS3 all day and night while I worked, and I got paid very little, so every cent was precious, we only just made ends meet, and there was certainly no fun nursery preparation for me!
And suddenly he woke up and went back to work and was fantastic from then on.
I think it took him a long time to really get that we were having a baby. I think the change began when my bump became visible, so hang in there, he may just be taking time to adjust. You know.. going backwards before he can go forwards..
