I believe you keep focusing on your positive changes. She is noticing for sure. She is not the measurement tool. You are.
Reflect back on the mediation process. Learn this skill. The mediator knows the process. Take this as your way of negotiation.
Your W asked for more time to think. You gave this to her. At some point in the future use this:
H:"W, I need more time to think about this" W:"Bla bla bla I need a decision now." or "Bl bla bla dragging this out" or " bla bla bla delaying on purpose" H:"W, I am asking you to give me the same respect I gave you. During our first mediation, you wanted more time to think about what you wanted to do about the house and I did not force you to make an immediate decision. Please give me the same respect"
