Thank you all for your comments and support. After reading through these posts and talking with my coach:
She echoed many of your comments. She also said my wife might be perimenopausal, which is true. That started about 2 years ago. Couple that with the genetic predisposition to mental illness and the messed up childhood and I have got quite a mess on my hands.
I know she is not herself right now, so I am going to get her some help.
I left a message with our MC and asked him to call me ASAP.
I am going to tell him about the suicide talk (about 4 different occasions in the last 12 months). Hopefully, he can get her some help.
If she files for divorce, I will go for full custody of our kids unless she consents to a pyschiatric evaluation.
I don't think going to court and getting orders of protection and getting her out of the house is the best thing right now. She is not equipped to be on her own right now, she needs more help than I can offer her.
