Are issues with an ex HR related or supervisor related in my case?

Broke up with my boyfriend (who our male boss hates for some unknown reason). I asked our boss if i could move my locker location to prevent any tension in the future (it was beside my now ex’s). This was my boss’s response. I don’t think I would tell my boss any issues we have anyways as I try to remain cool and collective at work, but aren’t any issues between a coworker (especially an ex) something that HR has to deal with instead?
