Edelweiss, Merideth, Crosstitch, Anne 327 and Anno...thanks for your kind words of support and interest. It's greatly appreciated.

Yes, my house is alarmed...and it's always on.

Second, My MIL went with me and Larry 3 years ago to a drug counselor hoping we could help mom see how she's enabling Robin in her behavior and use. It didn't make a dent at all. None...Zero...Natha...I mean she really could care less...as Mom gets older the more defensive she becomes in protecting Robin...why? Haven't a clue except Robin blames all her problems, all her drug use, all her failures, all her misory's on her mom and tells her that all the time...ALL the time. Mom had Robin put in a mental place for 3 months when Robin hit rock bottom 2 years ago...did it do any good? No...Robin called her and told her how awful it was until eventually mom signed her out and swore she'd never put Robin there again. Robin knows all the has to do is cry enough and her mom will rescue her no matter what.
Is Robin capable of violence? Most definitely. Mom's confided in her oldest daughter that Robin has hit her and left bruises...but will Mom press charges? No.
The reason I am leary of Robin is her schitzophrenic behavior on top of her drug use...all one has to do is pick up the papers and read where this type of personality mixed with drugs snapped and hurt or killed people. It concerns me, yes, because it's hard to preduct what and when a person like this will go over the edge. Robin ranted for 3 hours after Larry told her she could not come into our home as a drug user...who rants for 3 hours almost the point of going to the hospital? Someone who can't control their emotions and behavior...THAT concerns me. And of course, Larry says she blames me first and foremost.
Anne...we will continue to protect our home and there's no way we're backing down on this. Larry, as I knew he would, sees the reality of all this...it's hard when it's a family member so messed up and out of control. As long as he and I stand by each other and protect our home we'll be fine.
