I Need Desperate Advise,
I have a sister who is also a mother of 2. One child is 12 and the other only 6 months. She isn't married but engaged with a person she's been with for about 1 year.
For the past 10 years my sister shows signs of BPD (possibly BP). Her symptoms are much more like BPD then BP though.
Over the past few years things have been getting progressively worse. I only see her a few times per year but when I do things often get heated quite quickly. This could be literary over saying something as simple as today it will get dark at 5 and she would disagree and say it will be 515 (often she isn't correct though). She would defend her positions like her life depended on it and a sensible person has no choice but back down, as the subject of the argument doesn't mean anything.
Often we have had arguments regarding how she treats her daughter. She yells at her constantly, never things to explain things, and has to control everything. (especially small things like the way she sits, and even holds her fork). I have always bitten my tongue about these comments as I know my sister would "freak out" and blame me for interfering. Then I feared she would no longer let me speak to my niece.
During my last visit I could hold my tongue no longer and when my sister dished out a punishment to her daughter for rolling her eyes, I commented, "you're going to punish her for that", then all Hell broke loose. My sister swore at me, cursed me, and told me I had no right to come into her house and tell her how to raise her child. I just sat there and took it and eventually left.
My biggest fears are now coming true. My sister will not answer her phone and through email has told me her daughter no longer looks at me the same way (likely untrue, as even her daughter has made comments about her mothers anger) and that she may never take my calls again.
All these years I have "walked on egg shells" around my sister in order to ensure I have some relationship with my niece (until she gets older and gains her freedom). Now it seems I may have approached the situation in the wrong way.
I am looking on some advise on how to handle this situation? My sisters fiancée doesn't seem to want to stand up to her, but he is well aware of her anger issue. (Actually he has take my calls but said he wouldn't tell my sister).
I am at a loss here. Any Help on the next step I should take? My sister is very defensive about psychological disorder talk. We've touched on the topic before and it didn't end well.
