Need advice for a WW who left Part 4

[dwh15]

Spoke to my sister-in-law (one of WW's sisters) tonight for 30 minutes. Found out even more lies that WW has been telling, this time to her own sister and some other supposedly good friends. As people talk and exchange stories, the truth eventually comes out. So now even more friends are backing away from her. Her own sister, who initially urged me to hang on and try to make amends, is now encouraging me to let go, move on, and get custody of the kids.

I don't know what's going on, but there is more here than infidelity. WW has become selfish in the extreme, and adopted a stance of lying whenever and to whomever she pleases to get what she wants. I certainly won't be setting up any more meetings with her, or trying to reason. I can't trust a word she says. It was quite a wakeup call speaking to her sister tonight, who is one of the nicest, most caring, and generous people I know. WW is losing friends and family all around her. She's surrounded herself with a new social circle composed almost entirely of OM's friends. I am seriously starting to suspect a possible substance abuse issue, which my own sister has maintained for months now, and that is what she does - substance abuse counseling for women.

I guess it doesn't matter what the reasons are, but I know I can't trust WW at all, and need to try and separate her out of my life as much as possible. The woman I married and knew before has been replaced by a monster. I hope that some how, some day, she can start to at least partially resemble who she was, but I don't see it happening for a very long time. Thanks everyone for the support. I'll keep updating as the custody dispute unfolds.
