Funny you should say that....when my wife left me after 25 yrs...I had a form of PTSD....I was really messed up...for a long while...I could not control my emotions.....therapy didnt help....they just tried to get me on pills...which made things worse...and the therpist I was dealing with tried to rationalise the cheating...I was really put out by that...
I lost my whole Identity...I wasnt a husband anymore...or a provider...or a lover...and barely a father...
I had to remake myslef.
I reverted to my 20’s for a while...but I’m not in my 20’s anymore either...
So I said screw it...I dont have that many years left and I’m not going to live like this...I got out and made new fiends and met new women....I;m still single and not really dating...but I know my life isnt over yet....and i now look forward to each day instead of dreading it.
