Hi everyone, after some time away from the board, I'm back with an update....
Things have been topsy turvy here with DW up and down constantly. However, she's finally acknowledged she's not well and both I and her family are hopeful she'll accept treatment and drop the unprofessional counselor she's been seeing. (The counselor has shared her comments with me; affirmed her warped view that I and her family are the cause of her unhapiness and contradicted a trained Phsyc by saying DW is in fact 'not depressed').
It also came to light that DW had a terrible period of depression hen she was 17, something her parents only just told me. If on;y I had known, I could have been more vigilent after the birth of our son.
All in all, I've decided to stand by my DW, who having left the marriage is now questioning her decision. However, until she accpts she needs treatment, I cannot go back. I will stand here on the sidelines and support her however.
