Most Helpful Guy
What on earth is he playing at? Here's my guess. He still basically loves you, wishes things had worked out, but knows they won't/can't for whatever reason. So on the one hand he doesn't want to get back together, but on the other hand he doesn't want to move on and not see you anymore. So he tries to be friends with you, as a sort of compromise. But then this does not work because when he is with you, because of his old feelings, he can't help but make all these efforts that look a LOT like the sort of thing someone who wanted to get back with you would do (like taking you on a surprise trip, telling you he still has feelings you, telling you this new girl is not his girlfriend yet and kissing you before he leaves).
