There must be some resentment there from your sister’s side. Going from being the youngest in the family, to being replaced with another girl and then being given the responsibility of having to take care of you too when she should have been enjoying being a teen. Maybe she just accepted it when she was younger, but then as she’s got older the resentment has grown which is why she seems like she has a problem with you.Yeah that's correct!
I can totally see that and I've never thought of it like that! We have always been really close - my mum used to work all hours and my sister used to get me ready for school, take me there and then rush off to secondary school herself! She's helped my mum out looking after me a hell of a lot, I even lived with her and her husband when I was 19/20 but the problem is she throws it back in my mum's face alot and she likes to say to me "I brought you up! I was there more than mum was!"
We got along really well until I moved into my own flat, then me and my partner bought a house of our own, she doesn't seem to like me growing up very much! She's always looking around my house like she's searching for faults as well! I love her with all my heart she's my sister, but I've been saying for years that she's got a problem with me that she won't address
This is why I kind of wanted to keep some little details to myself - it hurts that she's not interested enough to ask me herself. Like I've mentioned it's not because she's upset about not being invited to the wedding, it's something more :/
I don’t think your attitude helps though and maybe she also feels you have never appreciated it all and that you haven’t thanked her for doing what she did. Maybe as you got older you became more petty and started behaving more and more entitled and like a brat and she felt more and more pushed out because of the relationship between yourself and your mum.
