I understand. It is hard. Believe me I know what you are thinking. I have the same thoughts. At the moment my W is not someone I want to spend the rest of my life with. Not like this. And the longer this goes on the harder it will be as I am setting thebar high for what I want. It has been so long since we have had easy fun together I know I will have a hard time if we do enter piecing.
But I will cross that bridge when it comes up. My W will be different if she wants to cross that bridge. Your H will be too. Don't rule anything out based on how he is now. How you are is also not how you will be down the road. Change is the only constant!! For now you only need to believe in the potential of a new future R.
Recently ye have had a lot of evenings together, even some on your own without daughter. There could be many reasons H was willing and eager to do that. But that is not my point. He does not associate you with negative feelings that make him avoid you or worse hate you. He does not love you like you want him to . Yes. But ye get on better than most separated MLC couples.
Anyway back to you. Put the focus on you and your plans etc for now. State your goals here so you are accountable. Many people like that approach but it isn't for everyone. Just keep moving forward for you.
Don't be hard on yourself for how you feel. It is not easy. We manage as best we can.
Best wishes
