Most Helpful Guy
I wouldn't spent to much time fussing over this right now. If he does really still care for you, I think you'll find out later down the road. The real question though, is which of the two options would you like to be true?

Don't overthink it. You've broken up 3 times already so obviously it's not going to work anytime soon. He probably misses you, but that doesn't mean you should consider going back with him especially if you have a new job and are happy. He should've appreciated you when he had you, you know?
