Meeting your old bully at a gay bar

You were, to be frank, bullied for being gay or at least appearing gay in highschool especially by a guy named Matthew. Despite this you took it in stride and go yourself into a good university and have been living the high life as a destitute student. You've joined some clubs and made some friends, some of which have lead you to a local gay bar to hang out on a Friday evening. While drinking at the bar you see someone at the other end on they're own, you know what it's like being alone, so you consider walking up to them, but then they look up at the barman and reveal that they are in fact your old bully, Matthew who made fun of your sexuality, what will you do now?
