Should I go for it?

well wen Istarted hanging out with this guy he said he doesnt want a girlfriend but now we have kinda been acting like boyfriend and girlfriend (no kissing or anything like that though) and i dont know if he wants a girlfriend now but I want to start dating him but Idont want to ask him out cause I dont want to ruin wat we have but people keep on asking me if were dating or telling me that we would make a cute couple and it sucks cause I want to ask him out but I am scared I will lose a friend a long with a boyfriend is I do. Its kinda like one of those situations wen it hurts to be with him but hurts even more to be away from him so my question is should I ask him out or wait to see what happens?
