TOH it is a tough place to be in. Should I stay or should I go now. Only you can decide what is best for you. I know that if I had filed, my h would not be around as he is today.
Also keep in mind this all takes time. It has been almost 3 years now for me and my h. You really haven't stepped back until now to let your h have his space to process life. You don't know what the future holds.
Just keep praying and ask God to help you with what to do. I know I would pray often when I was feeling what you are and then God would always show me a sign to keep standing.
