I may go out with a guy but my friend doesn't like him?

So this is pretty much a continuation of my question here: http://www.fluther.com/175935/my-friend-says-i-shouldnt-talk-to-the-guy-i-like/

So we’ve been texting everyday and from what I’m seeing, he’s really nice and accepting. He tries to get to know me and he always asks how I’m doing. We’re also into the same kind of things. I have a feeling he may ask me out soon, and I want to say yes, problem is, my friend doesn’t like him!

I’ve heard from her and her friend that he’s not nice, but I’ve also talked to a bunch of other people and they all said he’s really nice. So I don’t know who to believe! I want to hang out with him after school just once before we actually go out to see what he’s like when he’s not around other people, but still.

If I do go out with him I don’t want it to damage my relationship with my friend. She’s really nice and I know she’s just being a good friend and looking out for me, but this guy is really nice and I feel like it’s not really fair to him that I just listen to what one negative thing a person says and not talk to him at all. I don’t want her to be angry with me or think I’m stupid for going against what she said. I still want to be friends with her while at the same time going out with this guy I really like. Can someone help me please? Thank you!
