My mum used to say “I’m not proud of you. I didn’t do x thing.” I.e. the achievement I had made. I think she was trying to sound like she didn’t want to take the glory, but actually she was jealous and could only be proud if it was about herself. This was among all her endless criticisms and picking holes in my appearance etc, so it twisted the knife.
I say I’m proud of you now to my DC when they have really tried, achieved something, been brave etc and you can see how it boosts them and helps them to value their effort and achievements.
My mum still doesn’t understand why we don’t have a good relationship
