Im leading a guy on and feel bad and confused about it?

I think you're just retracting your feelings towards him because you told him how you felt, and you're scared of his sincere response. Don't be afraid to show your feelings if you know him really well. Just make sure he's not leading YOU on. And if he asks you out, ask for some time to think it out, assess your feelings, and then answer. Don't do what you don't want to do. I was in this kind of a relationship with a guy for two months. He is a great friend, and I thought at first that I was really interested, but I wasn't, and eventually, I was interested in another guy, and I had to break it off. Just use whatever you do as a life experience.
