A few weeks ago I met a man on a work do and we drunkenly flirted. He told me he wanted sex with me. I said I wouldn't and went home. But he continued messaging me asking me sexual questions. I was flattered so reciprocated. Eventually I picked up on a few things about him that made me realise he was after one thing entirely and I backed off. I think he was gaslighting me. He was making out I was crazy because I was questioning him over the rumours about him being a womaniser. I know I am completely better off without him but I keep thinking did I get him wrong. Should I have been kinder to him. I keep thinking about him but I know he is a narcissist. It's doing my head in. He's left now. And he blanked me after I told him to leave me alone.
