Eye of the tiger, I could have written your post (minus the "things happened"). I really relate to many of your posts.
I went through that false situation for 7 months, I'm just 8 weeks past the end of that now.
It's absolute hell, I know.
But the crumbs he's giving you aren't enough, and you're worth more. I'm glad to see you packed up his things, that's big.
I think it's about no longer having a person, set plans, just someone who you think loves you. My WH was my person, my most favorite person ever.
However, I've learned that I should be my favorite person, and my next SO a close second, but not to sacrifice myself again.
However, learning isn't always the same as doing, and it's not easy (at least in my point of view) to put into practice. I didn't do well with it this past weekend, I can say that.
Doing other things does create a sense of accomplishment for me, and distances me from the role I had in the marriage though. It makes me, me, not his wife. I hope it will do the same for you.
Sending lots of good thoughts your way.
