Congratulations on your forthcoming marriage, LeoKitty! I wish you and your FDH all the best!
I'm so glad you've decided to take notanan's advice if your sister contacts you. For all the reasons notanan said but also this: If she's partly a rebellious type, as I suspect, and you tend to be more of the "good daughter" (for want of a better expression), then your defending your mother is just likely to trigger the rebel in her and backfire on you.
Actually, I've been thinking about you and yours all day. Just some loosely related thoughts... I don't know if you're still reading or not, but I'll just throw them out there, in case you are and also for your mom if she's wants to read them...
- IMO, no one really "falls in with a bad crowd" - they CHOOSE it. But why would your sister make that choice?
- If they were truly a bad crowd, then I imagine there must have been some drinking going on even then (perhaps I'm wrong, of course). And maybe some drugs? (again, I may be so wrong - don't want to make any false accusations). This certainly would explain some of her uglier behavior, such as punching that girl for no reason. You say yourself, she's charming - UNTIL she's drinking
- .But why would she go for drinking, etc? Part of her rebellion,perhaps?
- Or maybe sis was self-medicating? Maybe she had mental health issues even then, the family was "too close to the forest" to see it/deal with it ? And sis didn't know what was wrong or what to do so she resorted to alcohol (and maybe drugs)? And that's why she joined this crowd - cuz they provided this stuff? Maybe not... just my thoughts..
- Despite whatever issues she has with BIL, she may feel he "saved" her, in a way, cuz he helped her get professional help and the right kind of meds? You and your mother may not agree with the dosage, and sis may have her doubts, but she still may feel that he is trying to help her. I don't know if you believe that she suffers from depression or if you've ever acknowledged the possibility. But that may be something she needs from you people if she's ever going to consider reconciling.
- NONE of that means BIL isn't controlling, etc. Could be he took advantage of your sister's mental health issues, thinking, "ahah! here's a person I can control if she's on enough meds!" Or not... But either way, sis may be grateful to him for recognizing/seeing her illness, which maybe nobody else did (but then again, maybe you and yours did see it, I don't know... just throwing out ideas...)
Anyhow, I'm so sorry both she AND your brother have CO your whole family. My heart aches for you people - losing 2 AC/siblings - Wow. I can only hope and pray that one day you are all united.... Sorry this is so long...
