I was a friend with benefits with a guy, we were sex partners but things weren't serious between us.  One day, this stranger messages me and tells me that she's his girlfriend and he's been cheating on her with me.  I guess she found his texts.  I was furious with him, can't believe he did that shit.  I wanted some revenge for her, I felt like it was my duty. I knew he had feelings for me,  so I "confessed" my feelings to him.  Over the next few days,  he fell for the bait and I really sold him the idea that I loved him.  After almost a week, after telling him how much I adored him and how amazing he was,  I just told him his a scumbug and  just straight ghosted him.

Apparently, from what I hear he was pretty hung up about that.  Even a month later, he just messaged asking for an explaination as why I ghosted him,  saying I owe it to him and he still thinks I actually loved him.   I wonder if that was too cruel.  Does he deserve any sympathy, am I the asshole?
