They didn’t even divorce; she just has that much disdain for her children and their late father.
One of the best parts of not having children with your ex is that you can badmouth your ex all you want. If you have a child with your ex, you have to be very careful about how you talk about them in front of your kid and when you’re away from your kid. The way you talk about your child’s mother or father when you’re not around them can seep into the way you talk about them when you are around them, and it can really hurt a kid to hear one parent being passive-aggressive towards their other parent.
Some people wish they had never met their ex, and in many cases, that’s fine. All of us have had relationships from which we feel we grew and learned, and others that felt like a complete waste of precious time we’ll never get back. You would think that if a relationship had resulted in two beautiful children, you wouldn’t wish that the relationship never happened in front of those children in question, but in this case, you’d unfortunately be wrong.
