Apparently I'm HOEING AROUND!!!!

So I have this friend (a guy)  that i had back in June and we were pretty flirty but it was harmless. We stopped talking in November, we just kept getting busy and couldn't talk. Back to the present I texted him last week because I wanted to catch up, see what he was up to. It was just a friendly chat. He started to ask me a bunch of questions like if I was single and if I had gotten into a relationship anytime. So I answered honestly that yea I did and I broke up with my ex because he was a douche and it didn't really cross my mind to ask him if he had a GF or not, it was mostly due to the fact that he kept asking me questions and he kept being flirty and how he always wanted to hook up with me (I never took him seriously). So then the next day I text him again and I finally ask him if he has a GF and he goes yeah i do. I was like wtf you were being flirty with me. All he says is that he doesn't care and he wants to flirt and hook up. I kept saying no. So then two days later he texts me and says 'I talked it over with my friends and cheating is bad for my relationship but i don't care. I just have to be discrete'. I didn't even reply to him. So then on snapchat he was like 'Nudes' and I ignored him. 
Then like a day ago his GF found out that he wanted to cheat on her with me and she sent me a video of her saying that I was a hoe and that I needed to stay in my lane and how she was "#KeepinHoesInCheck". 
I was like wtf are you talking about. And she tells me that he told her I was the one that wanted to flirt with him. 
When in reality I didn't do shit, I was trying to avoid this drama. I didn't want to ruin a relationship because I wouldn't want something like that to happen to me so why would I do it to someone else. 
Sorry for the long rant.
