Just wanted sex....

So i was going to go to this concert and a guy in my friend group said he’s going to also. I am in college and so my “friend group” can get pretty big to where I don’t really know them but I was like why not I can get to know him. So anyway we went to eat just to talk a bit more by ourselves and he said he didn’t know any of the singers music which I thought was weird. So I asked him later and he said he was just looking for sex 🙄😪 so idk what to do. Should I still go with him? Should I go alone? I don’t want to but I don’t know anyone else who likes the artist and is willing to pay for a ticket and is available and I would offer to pay but since it’s sold out the prices are so much higher and I can’t afford it. Maybe I should just sell my ticket? :(((
