You will never see me post a single unkind word about him on this blog.I knew when my mother bad-mouthed my dad, who was a child & spouse abuser, it was to make us feel bad whenever we wanted to spend time with him. We knew that our father was an asshole, but he was still our Dad (they didn't have laws back then to prevent abusers from seeing their children).
But, to his credit, SSG Dizzy is a great father and despite our issues and our impending divorce, I could have done a whole lot worse for a husband. And, though there are things that make me want to kick my dog and pull my dreadlocks out occasionally, you will never see me blog about those things.
It's not so much that it's private or anything (it is MY blog, after all). But, he reads this blog and for that reason alone, I should be respectful. The other reason is that we are working on remaining friends and good parents and thus it would be in bad form for me to say anything bad about him "in public" and in turn, would hurt our relationship and our kids.
If one must go on and on about an ex, set up a private blog or diary, only accessible via invitation or password and/or find a therapist or a good friend who you can rant to when your kids aren't around.
