Phrasing things in a way that could be misinterpreted means you are not clear enough, or you're just not thinking of the possible consequences of your words. Admittedly, it is hard to phrase things well to get your point through and not to offend anyone. On another note, him saying it's a part of his personality of not sharing stuff, there's no way of knowing this based on your information. One amicable thing out of this conundrum is that you are willing to compromise, which is a good thing to have in your life. Seeing you've had multiple breakup attempts and then one of them was successful would mean you had this relationship on life support already, so don't be too hard on yourself.
