Is it normal to feel that confused?

This is not a regular is it normal question as much as it is "please help" kind of question! So, there's someone I like. I've known him for almost three years now. I've always liked him but two years ago I start to fall really hard for him. I told him like a year and half ago. But he said he doesn't feel the same. I didn't cut contact and we kept talking even till now. Sometimes I tried to but he wouldn't have it. He keeps coming back as a friend of course.(Yeah I now realize that was a very wrong thing to let going). Anyhow, I've met this other guy. He's really decent and charismatic. I still know him well. He's a friend of a family member. He expressed an interest in me. Everyone at home is rooting for him too! Personality-wise, he's a good guy. Problem is I can't make up my mind. With the other one back in my mind I can't help but think about him, as in reality I talk more to that other guy - the one I know well but he doesn't like me. I still can't feel neutral about him.

Another major problem I can't feel physically attracted to anyone but him. I don't know how to like someone else and how to stop comparing. I feel I'm attracted to the new guy because of that. The 2nd guy is also headed towards commitment. So that freaks me out too. What if I agreed and then don't feel any love for him? I know some distance form the other guy can help but I can't tell him I can't talk to you now because he just had a huge argument with me a couple of days ago because I don't talk to him enough and try to stay away. I said it's not true and initiated talking. So, now I will sound like a lunatic. Have to ever had this kind of situation? You can't feel attracted to anyone because of your exes or crushes? Any advice would be appreciated.
