How do you cope when an ex starts a new relationship when you have children together?
How & when did he tell you? Did the new partner move in and how did the children take it? How did it work out?
Likewise if you met a new partner at what point did you tell your ex? How did he take it? Were there problems?
And what about everyone meeting each other? Did you? Or do you not see his new partner? Does he see yours?
Sorry for so many questions? I'm just thinking about the future and trying to think about potential issues.
