It must be very rewarding to receive so much support and kindness.You do realise that is only a reflection of your interactions here. It mirrors what others see in you.
Here is my reading of recent unfoldings. You are way less detached and accepting than I thought. This is not a criticism as we all know how hard that is to achieve. For me you came across as accepting the reality of where ye are. Understandably you still have hopes if not expectations. That is OK as long as it is not dictating your demeanor.It is necessary to keep you going, but should not be held up for the world to see.
You and others have touched on detaching so I won't go on about it. Livestrong have a good outline of this but it echoes what can be found here. Check it out if you need further help.
For me your W is reacting to something. There is something that is pushing her. I do not have enough info to know what but I have two top candidates.Firstly she is moving towards something (or someone)snd she is clearing her path. If your W is wayward it changes the gameplan.I personally would want to know. To date you have accepted everything because of your past poor behavior. That is admirable to a point. But if now it is just an excuse and not the reason, your W should not be allowed to continue to dump it all on you. I don't want this to consume you, but I wanted to voice it.
My second possibility of what is pushing you W is YOU. Are you interacting in any way that she could view as pressure. Why did she need to reiterate that she does not want to do anything with you? She has made her position clear. You have to accept and respect that decision, even if you don't agree.
I am eager to see what you do with your newfound resolve.Work on your traits. Become a better man. Your W in your recent R chat gave you new insights as to what she was unhappy about. Are there any valid points there that YOU would like to improve. Keep improving R with kids. Be a better dad. Improve your skills and hobbies.Work towards a better future. And have some fun
As always I post with the best of intentions.
