Hi I am in a similar place mentally as you are. The only advice that I can give you (and it was given to me) is...
What do YOU want? If you are still not sure then I would not make a move. I think you want to be 100% positive that this is the move you want to make. Look you cannot change her but you can change you. Are you making this choice out of FEAR? If you expect that filing will scare her into changing her mind you mind find that the end result is not what you had hoped for.
Personally, I think you can hold out a little longer. Can you say to your child that you did everything possible to save this marriage? Only you can answer that question.
