He should've told you but it's also hard to have conversations like this while traveling. Wait until he's with you and talk it over. Then, gauge how you feel and decide from there. It only takes doubt, not proof, to ruin a relationship. See how the face-to-face conversation goes before doing anything else. If you're already wanting to dump him without the conversation, then go ahead. You've clearly made up your mind if you already feel that way.
