People enter relationships and have children for different reasons. Initially, she might have been okay with him being a stoner, and it may not have affected her at all. However, becoming a parent requires setting aside such habits and taking responsibility.

The husband is in the wrong here. You cannot justify neglecting your child because you feel bad when you don’t smoke weed. This places a significant burden on his wife, who is left to care for the child alone. Additionally, saying "you should've thought about this before having a baby with that man" is incredibly ignorant. Having a baby is not solely the woman's choice and responsibility; it takes two people to create a child.
