We are still legally married, but have been S and in NC for 2 years, and I still have all evidence, including printed out copies of his conversations on FB etc., and phone bills of calls & texts and etc.
It is in a briefcase and the briefcase is between my desk and the wall so I never see it. But I know it's there if I ever want it.
Since we are not yet D, I think it's good to keep that evidence. Someday I may give him copies of it all after the D just so he will know that I really did know for a fact the things I told him I knew -- if you can follow that.
I doubt that I'll ever get rid of it. It's a reminder to me that I never ever want to get romantically involved with anyone again.
