Need advice..

So I’ve been talking to this guy for about a year now off and on. We hangout everyone once and a while but not 24/7. He works at jujitsu place and a airport. He’s a pro athlete. Super focused on goals. I work a 40 hour job and babysit occasionally.

The topic of relationship has been brought up multiple times but he says he’s too busy for that. But when we hangout I always get the vibe of he cares but is too afraid to admit it.

Is there a way to approach it easier? Or should I just keep working on what me and him have as is?

Any advice is helpful.
