I have been thinking about this thread today, and the whole focus on not confusing the kids/getting them to accept it's over.
It just doesn't sit well with me, this concept of denying kids stuff that would undoubtedly make them happy, just to ram.home the message that your parents are now separated and you will never get to experience time with both of them ever again.
Kids aren't stupid. They realise their parents are separated when one moves out. I don't think the message needs underlining 800 times in blood and tears.....
The message I would rather give my daughter is that, whether her dad and I still love each other as partners or not, she will always be the absolute centre of both our worlds, so we are of course happy to spend time together and be civil to each other, if that makes her feel happy.
She is 14 now (we split when she was about 5). After we all went out bowling then shopping today, she did say to me, imagine if that's what life was like all the time, if you and dad were together and spoke to each other with that degree of politeness, laughing at each others' jokes etc, constantly....
And then we both laughed, because we both know life isn't like that, and if her dad and I had stayed together, life would have been one long argument, occasionally punctuated by him swanning off to shag anything with a pulse, as remains his wont, despite his relationship with the OW. (You know that saying about when a man married his mistress.....)
I really like him as a friend. He really likes me. We were an absolutely wful couple. But we can absolutely have fun together with our daughter, and surely that is the very least any separated parents can give their child..... I know she loves us doing stuff together, because it shows her just how much we both really really love her.
