Sunshine,
I know this is from quite a bit ago, but have there been any improvements?
Like many of the other experienced posters here, it really is one of those things where the anger of what a partner or ex-partner doesn't or won't do, can double fold, meaning, there's the pain in less expectations, but holding onto it is like regurgitating the affair. It just keeps spinning and spinning when what from a kids point of view is, is usually confusion of the emotions of it all.
So it's kind of like, letting go of resentment and knowing you can't make someone do something they're not into, makes an open to be there for the kids.
That way it's not so bad for them and they have you to look back on as hold of strength and possibilities for their own future and their children to come
