um, if he's uber flirtatious-- then i would take that chance to ask him where you two stand in your relationship and tell him your feelings. don't assume guys know things if you don't blatantly spell it out for them; however, you could also just forget about him and just go after a new man, because a guy who gives you trouble, while you two are not together, is not the kind of guy you want to be with.
