The bible quote in your signature is wonderful. Try to keep it in mind especially when you are in the midst of something difficult. When you are with your H, don't show him fear, weakness & resentment. Show him love, strength, and confidence that says to him: "even though I love you with all my being, no matter what happens, I know that I will be okay." If you have trouble showing those things even in this dark period, examine your self-confidence. Bring yourself back to center by saying to yourself and knowing that you are a good person. That you have worth simply because you are alive and no deeds on this earth can either increase or diminish your worth. You are not greater than or less than any other human.
Release fear by putting your full trust in God, that he will guide you on the right path. In Psalm 56:11 the psalmist writes, "In God have I put my trust: I will not be afraid what man can do unto me." So don't be afraid. Whatever happens is what's supposed to happen in Gods plan for you. As I said before, you can also have peace in knowing that you are doing everything you can, diligently, on your end to save your marriage and make it better than it ever was before.
