I think it helps to look at things from his point of view- who wouldn’t want what he wants? A companion to share everyday life with, someone to be physically close to, to be company with, someone to go with you places, to eat out with you. He’s feeling and motivated by the basic human nature to seek human connection. BUT it is not your job or responsibility to fulfill his exhaustive needs for connection and company. You have your own life to lead and must make your own decisions how to lead it. It would be very easy to be swallowed up by his wishes, to be flattered by his romantic attentions, to have your own sense of self overrun and buried. Don’t feel guilty ever for putting yourself and what you want to do first. Go have fun on your trip and don’t look back.
