BM, continue to set your goals, get your credit built, get your bank accounts, finish your degree, protect yourself financially, make your plans as you work towards your single life. But, if you don't want to end the M then don't.
I asked before - what is your H doing to end this M? other than telling you words, his actions are none. Make him do the work to end it.
I'm not saying that as a method of DBing. I'm just saying don't do it for him. And for goodness sakes stop telling him every single plan and idea you have!! Quit writing those letters to everyone.
Write write write, but do not send. We are here for you.
Live your life while you are still living. Riding the trail less traveled.
