I am sure it will pass
but I am feeling it right now.
She has just landed an extremely well paid job and has a lovely life with her husband and kids.
My mother told me recently that she thinks I'm jealous of her. This is because she wouldn't have got that job without my mother giving her years of free childcare including staying overnight, and doing housework, when she had to travel abroad (in a previous job). I never had that as I am older and my mother wasn't in a position to practically move in with me when I had my DC. I can rationalise that and I know its not my sisters fault.
My mother also paid off all her debts so she could buy a house and paid nursery fees when her DC were younger.
I guess the underlying jealousy though is that she grew up with her Dad. I didn't as my Dad left when I was 7 and her Dad is my stepdad. She is confident, vivacious, pretty and slim as well. Everything I'm not!
My parents lost interest in my DC as soon as she had hers as well.
It just feels so unfair and I feel like a terrible person. AIBU?
