Hello
Apologies that this is likely to be a long post but am seeking advice as to how to manage a situation or relationship.
Sibling is 15 years older than myself and our relationship isn't that close. I am the youngest (with other siblings between us). I presumed age gap or sibling rivalry was to blame but have doubts and DP has suggested bullying which needs to be resolved. However, I don't know how to resolve or feel it would be believed (silly as I am mid 30s) but fear of causing drama and being shunned by other family members terrifies me.
As a young child, physical attacks would be the norm. This was seen by DM at times and blamed on annoying toddler / grumpy teen dynamic. I can't deny this as I can't recall my own behaviour at time but remember incidents of being pushed into wall, slapped etc.
As a child, my DM would be told I'd done things or broken things which were untrue and I'd be reprimanded / smacked for naughty behaviour.
As a teen, comments would be made about appearance. Hair, dress sense, weight etc. Sibling would borrow my clothes and not return them.as they looked better on her. When alone together, my sibling would tell me that my boyfriends fancied her etc.
During the adult years, the same narrative about my boyfriends would be told. Having spoken to my boyfriends at the time and DP they denied this and found it odd due to age gap that it would even be suggested. My choice of clothes, career (professional with no children), and holiday choices are always commented on in a very sweet but passive aggressive way. For example, I bought a dress for a wedding and was told it was beautiful and she wanted to borrow it for xyz occasion as it would be more suitable for that rather than a wedding. If I send birthday cards or gifts to her family, they never arrive (despite tracking) and Royal Mail has lost everything in the last 7 years. I don't receive cards or gifts but receive a message via DM saying that I haven't said thank you. When I say I haven't received anything, I then receive something within two weeks which is either an expired gift card or a gift card that was bought after she has asked DM why I hadn't said thank you for the item.
Recently announced our wedding date and my sibling stated that her and DH of 6 years are renewing their vows that year.
We have zero communication apart from family gatherings. If I am hosting I ask her DH what food to buy her as she is fussy (if I ask her direct she says she eats anything) and ensure I have enough in, but on the day it is wrong stuff and states not eaten that in years. DM then makes comments that my sister is going to be hungry as not been catered for. Every restaurant I book has nothing suitable on the menu (despite sending the menu round in.advance).
At family events, I am either ignored by her or really passive aggressive comments with smiles. I have often thought I am being too sensitive and dismissed it as sibling rivalry or age gap, but DP has suggested it verges on bullying due to anxious nature it causes and not wanting to see her.
As a young adult, I started standing up for myself more and laugh off comments etc. This resulted in either the silent treatment for years or tears to DF or DM that I was being nasty. Sibling is known for attention seeking and creating drama but it is enabled else family receive silent treatment. I have tried to ask what I have done and to resolve and get told there is nothing going on and it's all in my mind
I'm not sure what I am seeking from typing this out. I have limited contact to family occasions, cards at special occasions etc as I want to protect myself and not feel hurt, however DM now says I don't make an effort. Tried to explain situations and instances and DM doesnt believe as my sibling is lovely and sweet. DP has witnessed comments (and been brunt of comments) and suggested its not sibling related but bullying. I guess I just wanted to get this off my chest and see if anyone else has been in a similar situation and how it was managed.
Thank you for reading.
