My ex called late the other night and I missed it, does he miss me?

Things ended really badly with my ex (he wasn't over his ex, wouldn't commit, then got jealous even still, etc.) and I haven't talked to him for about 5 months, I've also been in a different country. I noticed he called late at night his time the other day, will he call again, do guys do that when they miss you or is it a booty call (even though I really emphasize things did NOT end well)
