I don't know how I feel...advice needed...?

I would go with the amazing guy. Because it sounds like he'd make a better boyfriend in the long run, and he's already confessed his feelings for you, so you know it's a sure thing. Sure, your boyfriend's got good qualities too, and you don't want to hurt him. But I think if you're looking for something solid and long-term... the amazing guy gives you more of what you need. I would break things off with your boyfriend and just tell him that you're not happy in the relationship. And then see where things go with the other guy.
