relationship advice!!

So I’ve been seeing this guy,Tucker, for about nine months now. I just recently started talking to this other guy, Ethan, and things went better than I thought between us. I never thought we would connect on a level as high as we are right now. I think I may like them more than I like Tucker. But they both have the same qualities but Ethan is more outgoing and caring about me. I don’t know what to do. I want in my relationship with Tucker because I know it isn’t fair to him.

What should I do? I feel badly about the whole situation. But I’ve been giving so much time to Ethan.

Please note: these relationships are long distant.
