A fulfilling relationship should be based on mutual desire and respect. Despite the intermittent fun and exciting dates together, mutual desire is replaced here by apathy and ambivalence. This is clear from his own words, his lack of curiosity about you, and the scarcity of his efforts to talk to you when you are in town, out of town, or out of the country.
His lack of desire for a deeper connection with you is likely to leave you feeling more and more frustrated and disappointed. Unless you are satisfied with a perpetual feeling of unrequited longing, I would get out of this relationship now before your self-esteem deteriorates. Stop seeking his occasional validation and hoping that he will change.
Beware though, when you do back away, he will probably re-double his efforts and start saying things that you may enjoy hearing. Although you might take pleasure in his pursuit of you once again, if you go back to him every time he pursues you, his pattern of avoiding intimacy by distancing himself will probably become more exaggerated.
In the future, beware of the person who pursues you hotly in the beginning and then loses energetic interest. People like that often are drawn to the chase, but retreat from emotional intimacy.
When someone’s interest in you becomes lackluster, it’s time to let go.
