I think you handled it well, especially given that you are not well practiced in these conversations. I know you "know" this, but it's harder to put into actions when it's your sitch, your emotions.
When your W says, "I don't want to lose you from my life", that's a great time to validate. Saying "You already have", while true, was probably a bit harsh. Gotta love the WAS's who don't want to lose the LBS, but that's why we say to believe nothing they say.
The best thing you can do, IMO, is to move back to the life you were creating for yourself. Good job overall.

It is not things that bother us, but the stories we tell ourselves about things.
