I don't think my H had a bad childhood either...his parents worked hard but were never rich...I don't think that they ever even owned a home....just rented and moved many times.
Apparenlty a life transition happens every 7-10 yrs. Becoming a father may have triggered your H...who knows? My H had one in 2001 when he quit his job of 20yrs after turning 40 and the medicated with a OW for a short time and now, 9yrs later he is doing the same thing after turning 50 with OW only this one must not be as psycho (yet) as the first one since it has been over a year.
I have been advised that IF he does want to come home some day, that I have him seek counseling to work on coping skills!!!!
I am going to post something to you on the alt!
