It's such a personal choice, i agree what's right is for you to decide.
I took my ring off 23 mo post bomb and 8 mo after he moved out. The only one to question me was my youngest daughter (13 at the time). Interestingly enough, even though I don't wear it, I very much consider myself married (while physically sep. there is not legal paperwork or anything in the works for me at the moment).
So, whatever gives you the most peace IMO is what you want to do for yourself.
