Workaholic ex says he doesn't have time to be in a relationship

Anonymous
Can anyone give me an opinion of this? My ex boyfriend just broke up with me after a year and a half because he says he doesn't have time for a relationship since he wants to devote all of his time to school (a very difficult major that takes up most of his time). He said he thinks I'm "awesome" and isn't interested in dating anyone else but this isn't the right time for him to be in a relationship but he might like to try again in the future. Also, we would fight all the time about how busy he is and how he doesn't put effort into the relationship and that stressed him out.

What are the chances of this guy missing me and coming back?

Also, he's never had a girlfriend before me.
