What do I do?!?!

Kaylee

So a couple months ago I was talking to this guy and I started getting more and more attracted to him to the point that I agreed to have sex with him and I let him know that but as soon as I did he said “I’m sorry Kaylee, I have a girlfriend” so I kind of let the flame burn out and didn’t talk to him as much. But the other day he randomly texted me and now we have been talking and at one point he asked me for nudes and I said “don’t you have a girlfriend?” And he was really confused almost like he never had a girlfriend in the first place. I said “what about Claire?” Because I was distant friends with this girl I wasn’t going to send nudes to her boyfriend just like that. So he responded and said “we broke up about a month ago.” And of course I was taken back from the statement I had to read it a couple times to make sense of it all. But he did and he was single again. What do I do? Do I give him another chance or do I just not talk to him because while I was talking to him the first time he did have a girlfriend. Please comment and let me know!
