My husband and I and our kids' mom have a pretty friendly co-parenting relationship at this point. It used to be very hostile between them and we used to not share any sort of information at all. Now with the relationship being a lot nicer, their mom is more open about sharing what is going on in her life and problems while I do not like sharing any sort of personal problems. I don't mind talking about some aspects of my life (works, school, kids).
