Sorry to hear the situation you are in, but I know you choose to stay for your D8 and other reasons that make it doable for you. I know for me it was hard when my exH was still living with me but not remotely interested in a true reconciliation. Kudos to you for being able to handle that type of situation.
I am glad your D is growing into a lovely young lady, I am sure you had more than a little bit to contribute to that! My own S7 is looking more like his father every day, which is good, as long as his behaviors don't take after him!
