I second that it's possible your friend is either introverted or possibly has social anxiety issues. The way you describe your friend, that's me...or at least, how extremely extroverted people have described me (seriously, your text is almost verbatim for what my grandparents said to me after I visited them once). If you don't know how to interpret 'introvert language', I may come across as quite rude, bored, and ungrateful, when I'm anything but. There's just been a miscommunication somewhere along the way.

If you still value this person's friendship, I'd say explain to them that you were hurt by their behavior. May turn out this was all a miscommunication. May turn out this person is indeed an ungrateful jerk. Either way, knowing is better than festering in friendship limbo.
