I think you hit the nail on the head. he does want to work on himself- and needs his "space" to do it.
him moving his things is just physical space so he can re-evaluate his life. he may not file. i would not push that. he may say that another 10 times and not do it.
all that is just words.
stay strong and dont talk about R with him- back to square 1- if he brings it up let it be about him bc he is telling you what he needs. this is about him. he is lost (not you!)....
sometimes guys just need to clear it all out- my H took all his things and i saw it as a way for him to see who he was and what he is made up of.....
just stay loving. if you want this to work then just SHOW him your changes. you have already done an amazing job...
