Im dead serious. PLZ HELP ME!!!!!!!!!!!! I'm begging here?

I'm dating this guy named Edgar. And he told me he's in love with me. And I believe him. He's a very sweet and awesome guy. But there is this other guy. Named johnathan. He likes me alot. And last week, he said that he's in love with me. But now I think I'm falling for johnathan. And if I dump Edgar, I'll break his heart. I'm soooooooo confused. What should I do? Thank u.
