<human>: So over the past year I've been reconnecting with an old friend, whom I also dated briefly. We are friends first and foremost, but a lot of pent up feelings led to us flirting with the idea of getting together, only to do it at the worst possible time. Either way, it ruined the friendship, and we went our separate ways. 

I'm now married and in an open relationship. Out of the blue, after years without contact, the ex and I began talking. Not much at first, but it gradually reverted back to old times: friendly talk became subtle flirting became outright flirting became hour long phone calls became "it's finally our time to be together like we always wanted." I stayed neutral and reminded him that I am married (should've stopped the conversation there, I know, but I didn't). 

Fast forward a little bit and we decide to meet up, because I'll be in town. We go out and get drinks and towards the end of the night, he asks if I would be willing to leave my husband for him (I'd like to point out, it was said in a very joking tone, so I don't think he was serious, though he has hinted it before). I just said, "you know I can't do that!" in the same joking voice, trying to keep it friendly. 

The night winds down, and he says he might be able to get out of work tomorrow so we can see each other again, as it's my last night in town. I agree, and he leans over and kisses me, maybe a 3 second kiss, and we say goodnight. 

And that's the last I heard from him. We had one short conversation the next day that I initiated, about something innocuous, but that's it and it's been a week. I'm not sure if I'm allowed to ask him what's going on, or if my only option is to leave it alone. But heart is just in pieces. Was this a game? Some sort of revenge? I just don't understand, and I feel bamboozled. 

Thanks, guys!
