It is ok to think about the "life you had" and what should have been. And you say perfect but really think was it? I have the same thoughts as you often and today I was the only single parent from our neighborhood at a town fair and it really hurt and I was like "this [censored]...why is it like this...what happened to my perfect life?"
But for me reality was it was far from perfect and she brought me down into a rut in many ways. So was your W perfect and treated you how you want to be treated?
You will get "yourself" back. Don't expect too much so soon. I am in the same boat with you in being down and up and down and wanting my fun self back. My daughter asked me today why I was so sad lately? We haven't told her yet. You can't be a rock and expect to bounce back and be happy all of a sudden.
I don't like the time heals wounds thing but it is so true. My STBX filed in Janauary and we have been in the same house battling thru this for months...and me suspecting their is a PA when she has vehemently denied it for 6+ months. I believe in Karma and if you have done right by yourself , for your kids and your wife in the past.....good things can happen in the future for you. Keep the faith and your a good person.
