Do "Friends With Benefits" end well?

I'm currently in a "Friends With Benefits" situation (protected).. However I'm massively falling for him. And he acts so loving towards me, cuddling on the sofa every night, he falls asleep on me, won't let go of me as we sleep in bed together, I cook him dinners, do him lunches.. It's only been happening for a month but I just feel myself falling for him. Anyway today, I confronted him and said I like him a lot, and we should end it if he doesn't want a relationship... He said he hasn't caught any feelings for me yet, but he enjoys being with me each night, & I'm such a nice girl etc... But he doesn't want to jump into a relationship yet... And can't gaurentee he'll end up falling for me. But he doesn't know where it will go. 
Shall I quit while I'm ahead or continue seeing how things go? I'm so crazy about him, I know it's quick but he's the best thing that's happened to me in a long long time. And I'd do anything for him.. I'm upset thinking it could be the end just because I'm rushing him... Does things like this ever end up in love?
