How long did you ponder over separating before actually saying it out loud to your partner?

I've always been super-depressed and the only thing that keeps me going is working out. If I get sick and i can't workout, I just go into depression.

But ever since contemplating separating, my mood has been much better and imagining moving into my own place is making me actually happy. I've been in this state for about 2 - 3 months now. But, I'm waiting for the right moment to tell my wife.

How long were you in this state?
