How do I handle a situation where I've wronged an ex boyfriend in HS?

I'm actually engaged for 3 months (wedding set up for Nov 5), have a great job position as a manger, both of our families get along and babysit as a hobby.

The awkward issue is someone with management experience just applied for my same position. So soon it's going to be two managers, me and him. In my total shock it's an old ex boyfriend from my HS years whom I've wronged in the past. The break-up at the time was on bad terms.

I know HS was a long time ago and I've come a long way since (learned from my past mistakes) but I wasn't expecting to really bump into him. We greeted each other but only spoke about job matters, nothing else. Needless to say this is so awkward. I'm treating him cordially as if it were any random manager. How do handle this situation?
