I think I'm leading a guy on and I don't know what to do
So, in senior year I identified as bisexual and I had this like flirting thing with a guy. He was an arrogant dick who was also kinda transphobic and stuff. Well we never did anything more than flirt because I'm non-binary and he only saw me as a girl. Then two days later he asked to see my tits. So, yea.
Well, then I dated a guy for like four months and broke up with him for several reasons. But mainly because I realized I'm a lesbian.
Well two years later, out of nowhere the first guy messaged me and we've talked for a few times since (messaging). But some of the things he's said makes me think he's still into me. And I'm definitely not into him. It says I'm a lesbian on my insta profile, I've posted at least a couple stories on insta that mention I'm a lesbian. All of which he's had to have seen. But haven't actually said to him that I'm gay.
Granted I'm only assuming he's still into me but like what should I do? I'm definitely not into him like that anymore but I'm kind of naturally a flirtatious person and I don't have much of a social circle so like it's been nice talking to someone who isn't family, coworkers, customers or my one friend.
I don't know if he's still as arrogant and bigoted as he was, two years ago but still, if he is then I don't even wanna be friends with him. But I don't want to stop messaging him completely if he is an alright guy now. Like I'd like to be friends but I do not have feelings for him. So, again I'm still just assuming he still likes me, but if he does, what should I do? Should I just tell him outright? I'm not really hiding it and he had to have seen it on my profile and I know he view my insta story but still. What should I say/do?
