Here’s the problem you are not detached so in essence you’re not ready to file. If you were detached limbo would be a piece of cake for you. It’s easy for your W because she doesn’t want to save the marriage. I suspect you think filing will either wake her up or make you feel better. I will do neither. I was in limbo a lot longer then you and when times got tough I would think about my children and get up and prepare for another round.
I have been listening to a lot of Peter Crones podcasts and one of his famous quotes is “Life will present you with people and situations to show you where you are not free”. The point is all of life is uncertain and you better get fuching used to it. You have to learn to be ok that you don’t know the outcome and you’re ok with it. Trust the universe.
So my suggestion to you is to work on being detached so then you can make a decision that is based on logic and not emotion (fear)
Life is $hitty sometimes and it will punch you in the face like a MFer. The goal is to keep getting up to go another round. If you need a reason just think about your young children.
I’m not going lie, it’s not easy but it builds character.
