should I talk to him?

I dated this guy I liked for a brief time about 7 months ago. We have become fairly good friends since then. Neither of us have really made an effort to try to get back together. He has asked me to do things and vice versa. Were both pretty shy especially when it comes to making the first move. My friend came to me and told me she liked him and asked me if it was ok to persue him. I told her yes, but shortly after I realized that I still like him. She really likes him, but I also know there is litle to no chance for her to go out with him. I love her to death and not to be superficial, she is not his type at all. I also think there is about a 50:50 shot at him wanting to get back together. Should I go behind my friends back and talk to him about how I feel or back down? I dont even know if it would really work between me and him, but I’m willing to figure it out if he wants to.
