I think communication is key. No matter what the reasoning was for him taking off, it's best if you've been offended to take it up with the offender. He may or may not respond how you want him to, but nevertheless at least then you're letting him know. He can't do anything about it if he doesn't actually know how you feel about it. Pretending nothing's wrong would just make your hurt fester into something worse. If you say something and he responds badly or doesn't care, you can write off the romance with good reason, and if he does respond in a way that is supportive, you'll be able to move forward from this.
