The situation
A man and a woman have child together although they aren't together. The father is in a relationship with another woman. Father asked the mother to send him a picture of their child and the mother sent him a picture of the baby while he is nursing/sleeping because she doesn't want to wake him. The Fathers lady sees the pic and tells him to tell the mother to not send anymore nudes. Father does it
Who's in the wrong? How could this have been handled better?
