Why are you afraid that he'll do what you asked? Isn't that what you wanted or are you looking for a reaction? You know, if you put out a boundary and/or request....YOU HAVE TO MEAN IT! It's not done to get a reaction or hope that he will coming running back w/promises that never happen.
Learn to set your boundaries and truly mean them. Your last paragraph tells me that you really haven't changed if you are afraid he'll follow through on your request. Either you want him to leave you alone or you don't...you need to make up your mind and stick with the decision.
Actions speak louder than words and you need to practice each and every day what you learned while away on your trip. You do not want to fall back into old patterns. Until he sees that you actually mean what you've said, he'll continue on his merry way and not do anything about the relationship because he knows he has you hook, line and sinker. You are that little fish that is hoping that when he drops his line you'll be the first to gobble up the bait...guess what...it's better to be the one that is hard to catch because the work will make him appreciate you all the more.
Bottom line...respect yourself and others will respect you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
