I have read several things the last couple days that make me realize how lucky I am.
My ex and I don't have a custody agreement at all. It's verbal. When I told him about homeschooling the only thing he had to say was could *I* handle it (being having Brianna home all the time with her current behavioural issues). He didn't question whether I had lost my mind or that there was no way I could teach her, just whether I thought I could handle it.
I'm now seeing how much problems he could have caused but didn't. He's even purchased curriculum for us and helps with Brianna's French (his family is French, I am very much not). If I'm having issues with Brianna dawdling or whatever, he speaks on my behalf to her rather than telling me just to put her back in school.
As funny as it sounds, I feel very lucky to have divorced the person I did.
