I don't think I like him.... But Idk what to do?

So my friend has set me up with some guy.... let's call him Andrew. I talked to Andrew all yesterday and he seems really sweet and stuff - we even both plan to study the same thing in college. (He's 19 I'm 17). but once we all made a group chat on snapchat to talk to each other, he is a completely different person. He makes jokes about other cultures and stuff (which i really don't like), and also kind of acts like he likes my friend (????) even though she has a boyfriend (idk i might be tripping). He is also in a friend group i can't stand and he is starting to act like them. I had a thing with one guy in his friend group back in the school year, but I broke it off because he was just using me for sex - he literally didn't talk to me after that even after he told me he really liked me. Ouch...

We are supposed to go meet up with him today but idk if I will like him and I don't wanna hurt his feelings... plus I really don't want to hang out with his friends 😭 they are douchebags. I don't know what to do.
