So... again.. im on the fence here as only you know the exact personalities but
Option 1 - the quiet life. You are NC with Sis, but your mum visits. The packages are small, you keep them all in the same place when they arrive and hand them over to DM, no discussion. (TBH I would probably do this as its much easier and time with your mum is about you and your mum , not all about your annoying sister.) Your sister lives in another country. Your mum in another. At the end of the day, all contact is up to you really. You could just lower your expectations of both of them. Smile and wave when you see Mum for a few days a year and let them both get on with it, whilst the main focus of your life remains your own family.
Option 2 - Give Mum the packages as they are here anyway. But take the opportunity to raise some issues with your mum. Maybe sitting down somewhere quiet not at your house... and go through the list.. but more in a questioning way than attacking way... ie...
- I've always been upset that you wouldn't come to my wedding, but you said you'd never miss Sis's wedding...
- or ...What do you think about the way she said a b or c to me or called me a thief ( this may need follow ups.. Do you believe I am a thief.)
- Or more interestingly.. Mum. Why do you believe I should stay in contact with someone who treats me like this?
Mum.. whilst she keeps sending me packages and then calling me a thief, I'm not willing to be in contact with her.
I'm thinking about talking to teens here.. asking how she would deal with the various issues with someone behaving like sis... What would you do in that situation.. and discuss.. You don't have to come to a conclusion.. you can just end with, well I will think about what you've said Mum, what is your take away from this?
However, this could lead to quite an uncomfortable time for both you and your mum. It would ONLY work if it was a calm discussion with no trace of aggression or accusation, more along the lines of wanting to find out what she really thinks and how she would deal with it in your position and why.
I suspect that what you really want is to feel that your DM is on your side, that she sees how unpleasant your sis behaviour has been and understands why you are NC, but as a Mum, I know I would always try to support both parties and try to see both sides point of view and would defer a decision until i knew that. Unless it was overwhelming. I would be working from a point of view of trying to bring siblings back together.
Option 3 - Nuclear. Send the packages back to sender and tell Mum its NC with Sis all the way. If it were me I'd try one of the other options first. But consider if Sis is really doing this to wind you up.. or if she's really dense and really just sees it as a practical way for Mum to collect her packages and can't see any problem with it.. Is it her way of trying to stay in contact without admitting it? I think if I was going to do this... I'd pick up the phone first and say why are you doing this?
So you've got two issues.
-
The lack of support and some of the comments by your Mum which make you feel like you matter less than your Sis.. and your feeling that she supports your sis and not you ( which is only a feeling as none of you are really talking to each other) Which in a way is separate from your issues with Sis and between you and your mum as sis can't control it. But I suspect it may still be the root of your issues with Sis. - there must be a reason why she's so mean to you.. Does she resent you in the same way? Is your Mum the divide and rule type?
-
and your Sis's very mean behaviour towards you. And I can understand this makes you angry and you want the behaviour to go away. there must be a reason why she's so mean to you.. Does she resent you in the same way? Is your Mum the divide and rule type?
Maybe its worth it to get to the bottom of the situation with option 2 - honest talk with mum - but I'm not an expert, so you'd have to think about whether you wanted ot open this can of worms. and maybe there are other options anyway.
Maybe try Option 1 for this visit, unless you see an opening for a talk.. but then see a therapist to discuss strategies for dealing with it for the next visit.
Realistically you need to think - what do I want from my Mum?
What do I expect her to do, even if she agrees Sis is out of order?
In an ideal world What would be the best possible outcome from all this? for me. for Mum and for sis.?
