relationship... help?

Tapanga
So I met this guy at one of my friends birthday parties and we were joking around with our group of friends and he seemed pretty cool. A few days later my friend tells me she gave him my number and that night he started texting me. He seems pretty nice and we ended up texting until about 1 in the morning. I had to go but he said he'd text me tomorrow and we've been texting  all day. He seems really nice and we set up a few times to get together. Twice with friends and one time we're going to go skating together without friends. 
I, being excited, told some of my friends and they all had something to say about him. 
One of them said that she didn't like him that much bc she's in band with him and she says he hits on a lot of girls. The others were pretty excited for me and say he's pretty okay. 
I've had my fair share of bad relationships and wasn't planning on getting into another after a bunch of horrible stuff when down last time but I want to get to know him a little better. 
My problem is that while I want to get to know him better, I'm worried I won't be able to trust him as much as I should not only because of what happened last time but because of what that one friend said. 
Do you guys thinks it's a good idea to see for myself and make my own opinion of him? Or should I just stick with what that one friend said and just not mess with him? Im willing to give him and myself a chance bc I think I'm ready. It if you guys could give me your input that would be awesome. Thanks and Sorry this is so long but I really need help. 
Edit-- Thank you all for your advice!
