Broken Marriage

I have these two beautiful babies. My greatest blessings, greater than I could have ever dreamt of. And my marriage is completely falling apart. I don’t know what else to do. My husband is very good at saying all of the right things, but when it comes to action he rarely steps up. I have given up so much to stay. To fight for him, to keep our family together. I’m now at the point where it feels like I have to completely give up any self worth that I have left to stay. That I just literally need to choose to be numb so that whatever he says or does or doesn’t do, doesn’t hurt me. After all that we’ve been through, what I truly want most is for our marriage to be healed and to grow together. But I can’t fight for our marriage for him. So I just don’t know what to do anymore. I am looking for guidance, for a sign, for miraculous intervention. I am just so lost. I truly believe that God would want me to be joyful in my heart like I once was. I just don’t know how to keep holding onto this.
