is this your first child?
there are men who are very stressed by babies.
maybe at this moment try to understand that he does not want to vent his stress at you, so he sleep in the other room.
when you say men's needs, you mean that you have just given birth so it's not convenient for you right?
one very important way to solve your problem is communication.
the biggest problems between couples is they dont't share or express what is wrong.
you see if you can talk to him, message him or worse still, even if you have to quarrel with him, get him to say what is wrong.
if not...you try and see if you can let him have his cooling period.
like i mention before, some guys can be very stressed by babies to the extent that they can be depressed.
and do remember to show some care for him in case he thinks you care more for baby than you care for him.
