Not sure how to approach this...
I am NC with DM (got taken away from her as a child) so only in touch with DF. And my toddler DCs are very close with him. But I hate being around him with them because of his attitude.
He is basically disrespectful in constant small ways. Asking my DCs in a 'lighthearted' way -'will you be cleverer than Mummy when you grow up? You'll definitely be better at maths than her!' They were just confused because they didn't understand why he would say that, my 3yo saying 'Are you joking?'
He consciously/subconsciously undermines everything I do with them. For example if I say 'it's bathtime' he'll announce loudly 'Let's all watch a film!' or if he's carrying one and I go to wipe their mouth he'll put his shoulder out to shake me off and walk away.
If I want to say anything to him I have to raise my voice and repeat myself 3/4 times because he just ignores me. Or rolls his eyes/sighs with exasperation/contradicts what I've said. Or it's a battle with him, so if I say they can get up from the table and they fall over (for example) he'll make a face and look at me as if to say 'See?'
And he was carrying them upstairs to bed and I was saying goodnight to them and he abruptly says 'That's enough' and walks off with them.
He'll ask his wife for advice on the DCs right in front of me and ignore the fact that I'm right there. He will never ask me for advice or permission to do anything with them.
It's hard to explain because it's just little passive aggressive things all the time. It has been like that since I was a child and it deeply affected me. I told him how I felt yesterday - that I wanted to enjoy being around him with the children but didn't because of these things - and he said 'I know you have your issues and I suspect these things happen far less than you imagine they do.'
I can't go NC because the kids love him and he's all the family I have. But I hate how he makes me feel and I'm terrified the kids will start picking up on it and lose respect for me/treat him as the authority.
WWYD short of going NC?
