In this situation, I don't want to repeat the same mistake. I want to give my brother one chance - and only one from me - to get his shit together. I'm concerned that on some level he thinks none of us cares... noone seemed to care what happened to my dad.
As to typing them... my dad took the MBTI as part of a severence package and typed as ISTP. I gave my brother the Kiersey (unofficial version) and he typed as ISTP. I could go into superficial traits (epicurian, egalitarian, detests authority/rules, likes beer/darts/cars, etc. but he's already taken the damn test).
My sister in law asked if she's doing the right thing by telling him she'll leave with the kids if he doesn't go to rehab. I said she is.
She is not thinking rationally at the moment and keeps going back and forth. She still thinks she can get him to change his behavior, if only she could find the 'secret password.' She is alone with him in Texas... she has no one else to help. At this point I'm rambling on a tangent. I've told her that any choices she makes from this point on should be solely about what is best for her and her children, and not about what may or may not get the desired response from my brother.
He's about to lose everything; this is just my 11th hour brainstorm to see if maybe, possibly, there's a way to get him help.
I know he has to want it... I'll ask her to call a professional interventionist and let them advise her.
