I have to say that I agree everything that HS has just said, because I've been bothered by all of the BS you've had to put up with since I've been on this board. You have done your absolute BEST to save this M, and she is still being as selfish as anyone I've seen (and like HS, acting like a teenage). She seems to be having an MLC and can't grasp what she really needs in her life.
I hate to be so negative, but I also hate to see you put up with the pushes and pulls from this woman. She is being insenstive to everyone's needs but her own (and I don't even think she knows what her needs/wants are!).
Okay, just thought about something and I'm sure I don't know what the hell I'm talking about here, but thought I'd throw it out here: Has she gone through menopause and is she taking hormone pills? I only say this because I remember back in high school when my mom went through this and she was very emotionally unbalanced. Just a thought...
Take care brotha -- hope you with find a tunnel with some cheese that continues to replenish!
