Congrats to you You must be breathing a sigh of relief, but it also must be kind of scary, this new 'chapter'.
What about giving it a little more time first? It would be really sucky if he has something up his sleeve.
But then if things don't pan-out, perhaps talk to him, but base it on more of "In the past, when you do stuff like this (make promises you don't keep), I would just act mad instead of being honest about my disappointments. Since we are trying to give this relationship a fresh start I know will be more forth-right with this type of reaction, rather than just act like I'm in a bad mood, and leaving you guessing" And offer some type of solution YOU find acceptable IE: Maybe in future, we could keep surprizes under cloak, that way if something comes up and it can't happen, no one feel badly after. or something like that..
