Umm ... No, he's got other stuff, if you call him your ex it's pretty sure he thinks of himself that way. Guys do pretty quickly. He's moved on, I'd say, from what you've said + his note. Unless...

Unless he needs you for something, or needs something from you. He wants you to remember, doesn't he, that "you are a good no great person who offers everything and who doesnt expect anything in return!"

You're torturing yourself with this. I don't know the rest of this story, but I hope you'll be good to yourself & get over him so you can be ready for a guy who's ready for a good woman.

But stop expecting nothing. You have the right to expect to be treated decently & to be given respect, always.
