yeah my dp does nothing at night either. the bfing thing is a factor, but i have gotten to the point where i've been begging him for more help.
it's hard though, cos i feel guilty that he has to get up and go out into the world and face people evryday. whereas if i'm tired, i'm at home with ds iykwim? i used to absolutely hate having to go to work tired so i try not to put him through that.
