Gonna miss him while he's gone

My boyfriend and I haven't been together long, but we've hung out almost every day since we made it official, so we're kind of clingy. We've also been friends for a while now, and I recently found out that he's liked me fore a long time. He leaves for Hawaii tomorrow for 2 and a half weeks and idk what to do until then. I spent the day with him today and I wish I would've hugged him more😭 any ideas on how to pass the time?
