I think that the kids will have an understanding to a degree that it was their Mom behind things since she is the one that moved out 6 months ago and because she is the one that has spent precious little time with them.
I suppose that I'm willing to let them beat on me both metaphorically and physically in their pain and frustration. I'm a big strong Dad, I can take that. What I won't stand for is their thinking that I didn't try or that I divorced on a whim or that I wanted it. Those things I think I can manage until they are old enough to hear the good and bad about their parents. I also have no intention of sugar coating the things that I've done. That of course also will be tempered with the understanding that they don't need to know too many details.
Thanks for the sig file, I will have to remember that.
