Just let it go?

I was dating/seeing this man for a month, he went out of town for work things this past Monday. We broke up (my overthinking made me end it). He was supposed to come back Thursday, but extended his stay I’m assuming because we broke up. But we talked that night. But since then, he hasn’t made much of an effort to talk to me. I know he’s back with his family whom he’s rarely sees.

He knows I like him & he likes me, I’m sad & miss him, I wish I talked to him instead of ending things. Should I ask if he’s done with us? Or wait until he’s back to speak with him in person?
