If you had a child with someone and then got divorced would you still have "family night" where you made dinner for your ex and played games with her and your child? On a regular basis? My husband's dad and mom are divorced. For a number of years mother in law was invited to father in law and step mother in law's for holidays if we were all going to be there. But it was only on big holidays. If it was a birthday for one of the kids, they were very nice to each other. But there were no attempts to do movie night or game night or whatever on at least a weekly basis. Bro and his ex are doing this a LOT. Ex sister in law is at ALL family dinners at my parents. As I cannot stand the woman it is not fun for me or my family. My kids cannot stand her either. I am just wondering if this is some new trend, because I have not ever heard of a divorced couple acting like this. Sort of like they are married in two houses with separate finances. It seems very odd.
