Congrats on the weekend! Sounds like you both really were able to have a sustained connection over the 3 days, which is really quite something! As usual, you were pro with handling the boundaries and balancing of things.
I'm interested to hear more about what you mean re: "significant internal changes since separating". Also, this: "I don't see you in my future, but I'm not discounting that you might be". was almost identical to my W.'s version: "I can't really imagine us together, but I can't really imagine myself with someone else either" and "I could see that we could stay together and it would all work out fine, but I could also see us not together and it would be fine too".
Love the clarity that this brings!! Wish I could have let it roll off my back like you did, MM! I look forward to hearing what comes next. You know, it sounds like putting some limits on stuff like the sexual interactions might have actually brought more closeness and greater comfort with each other. I'm with C_K...I think this is a good deposit in the ol' emotional bank account that you have together.
