I feel like I’m being manipulated

So I’m am just dating this guy and getting to know him. It has been nearly a month of us talking and one of our first fights happened and he is making me feel like shit for it.

I went out to the bar with one of his best friends/roommate and another person that knows the guy I’m talking to. They both told me to straight up leave the guy I’m currently seeing because he has a reputation and that he won’t change.

The next morning I texted and called the guy saying “hey I don’t want to progress things further because I heard some things about you that make me question if I should still talk to you”. He got angry at me for not knowing his character well enough and he is making me feel like I’m in the wrong about this whole situation. I was just trying to protect my heart. He said if we go forward that he’s gonna have a hard time trusting me because I believed what they said and to top it off all of his friends said “fuck her she’s not worth it”. I just feel like shit and Idk if this is really my fault or not

I was just trying to avoid red flags.

He told me his parents said that he has no dignity if he continues to talk to me
