Been there, done that. My partner was upset but people fall asleep when they are too tired. It happens with or without a baby. I would imagine that people can get really exhausted taking care of a newborn baby.
Sorry to hear that you are going through a difficult time. It is a wonderful thing to have a baby/starting a family with your partner, so don't give up okay? You may private message me too if you want to talk and feel that it is too private to discuss on the forums. Take care!
