My exH had a model divorce, honestly. Everyone was impressed including the judge who finalized it. We never fought. We just agreed. Everything down the middle. We always put our kids first and they never saw us fight once throughout the marriage or the divorce. I have championed their father.

Recently, my eldest son 10 has been making comments that his father has said in casual conversation. 'Dad said you could do that without hurting the windshield, but he says you're not the smartest person...'

After that I text him and said 'Hey. You can't say stuff like that even if you're joking. It doesn't help the situation. Please do not talk negatively in front of the kids even in jest.

He said he never said that and My son was lying. I let it drop. I never mentioned it to my son.

2 weeks later, My son mentions in casual conversation mentions that my ex told him I'm irresponsible with school papers because I lose everything. There was one test that I looked at and my son left in my car after I checked it. But that's somehow my fault. The paper was turned in. He got credit but this one even apparently allows him to tell my son that I'm not allowed to deal with homework because I'll just lose it.

Then when I called his Dad about it, again, exH said my son is lying... So I put him on the phone and he REAMS my son. Finally DS ten hangs up and said 'I shouldn't have said anything. Dad told me not to tell you things we talk about at his house.'

And I said 'You never have to lie to me or keep anything from me and it's not nice of him to tell you that. I will say that I'm your mother and you can always tell me anything you need. I asked him when he had this talk with him. My sons response was 'After you got mad about the 'not the smartest person' comment.

Now I know my son isn't lying (He's not known for lying. He's typically very honest) and I called his Dad and called him out. I never mentioned being upset about that so I know now that my exH is lying and my son is telling the truth.

ExH said that he's taking things out of context and turning jokes into gossip and blah blah blah.

I said if you can't say anything nice about their mother just don't talk about me at all. This isn't right what this does to children. You make them feel bad. I'm their mother. Don't talk bad about me. EVER.'

He's such a piece of crap.

I let my son know that it's dropped and that he should ignore his father's comments.

This sucks.
