opinions please ..

so lately my brothers friend has been checking me out & what not & i was like ook like he cute wateva so i been checking him out too lol. so we talked a couple times & it was kinda flirty. then earlier i was on instagram & i seen my brothers friends instagram pop up on the “other people you may follow” list so i checked out his insta & well it turns out this guy has a girlfriend of 3 years & now i don’t know like if i misread things but even my friends said it was flirty type of thing & well now i’m just sad lol.

just needed to vent aha comment what y’all think about this.
