Why did he called me so much? is this a red flag?

I hit it off with this guy on a dating app. I gave him my number yesterday and we face time til midnight. It was going so well. We even kiss through face time for NY time. But at the end got a little weird because I feel like he was distracted texting whoever it was (assuming girls). I told him the first time ima go since he seem distracted texting someone. He said no and he wanna talk, but he kept doing it… so I said ima go sleep. Then he called me at 3am, 7am, 8am (total of 5 missed calls), I’m sooo damn confuse why so many calls and so early? Was he trying to be sweet to say good morning? Is he secretly taken and the girl is calling me? I feel so weird, confuse, and paranoid.
