Lets talk about boys...oh no!

Have you ever had it where there was a guy who was a friend, and that was all you wanted to be was friends, but he wanted more? I kinda went through something like that a while ago but I told him that I didn't see us having a relationship because I'm a Christian and he isn't and I know thats wrong. So he decided he didn't want to hang out anymore because it would feel awkward for him. I continued to talk to him because I knew he needed spiritual help and I was the only Christian example for him. He would get angry with me and tell me that everything I believed in was a fake and I was an idiot for trusting in something so rediculous. Now I've experienced too many wonders in my life to even have a doubt that God doesn't exist, and nothing can rock me from that point. Recently he got in contact with me again and we started to hang out. Now some of my friends are worried that he is going to try to persue me again, but I honestly think that he just needs someone to help him and to talk to him. If I ever felt like he was trying to go after me then I would definately pull out and tell him that we can only talk, not hang out. I think he is sincere, but still some of my friends worry. Am I right in trusting him again? Should I be hanging out with him again or is there something I am missing? Please comment!!!
