I understand the thoughts of pres and isolation or depression. My h did the same thing last year and now again thisbyear but during both instances he ran to another girl. Please don't think that I am saying that ab your h...I mist wanted you to know that you are not alone.
However during my h first time of wanting to start his whole life over in whcih he only was tsxting with another girl...he later described it as a form of suicide so I do think he has some deep rooted issues.
I also tried to look for ptsd support for withdrawn guys but could not find much. Maybe check the va...that is something I wish I did while my h and I were still together.
