Only you know when you are ready to file....my W came to me about 9 months after our separation started and indicated she was ready to move forward with the D. I first told myself I would stand for 6 months and then re-evaluate. After 6 months I felt that I could make it a year so I continued. I never got to the one year mark so I don't know what would have happened.
If you choose to stand and essentially be in LIMBO you really have to let her go and move on with your life. If you don't and continue to hang on her every word, her every action and follow her on SM it will be very rough for you and you will delay the healing process.
