What do I do about this guy I haven’t seen in ten years?

I just moved to my hometown 3 and a half months ago. This guy connected with me a month ago. We dated (not seriously) for a summer ten years ago. I never slept with him. Anyway, we connected and since then he has rescheduled me twice and lastly offered me to join him and two of his coworkers at an expensive dinner. I invited a girlfriend but he said he wasn’t going to treat us just to be clear so I just skipped. Today I told him how I felt that I was confused and annoyed. He called me and I didn’t pick up. He then said let’s meet for coffee I didn’t want to pay for a stranger. I told him in text I don’t know if has time for a coffee tbh. Should I call him back to work it out or just drop him?
