Dear heartonhold,
there are a lot of us who has or have had the same problem. First, you need to decide what you want. And then talk to God.
Also, from my personal experience, i made a mistake for just asking God for reconciliation, it did not happen right away. So, i realized that i must have sinned, and i repented my own behavior, that drove my husband away. After that things got better. Still, we are separated for right now.
It is important to have moral support in your situation. Feel the presence of God. Right now, I am concentrated on growing in the knowledge of the Word, and also I pray for the reconciliation.
Pray to the Lord for things according to HIS will
Believe He has heard you
Believe you have received it
Wait in expectant HOPE, and RECEIVE
