Uh no. I see plenty of cute guys, some I even have a hard time forming a sentence around.
But I LOVE my boyfriend. They are very different.
Just because you think a guy is attractive does not mean you love them.
As you said, your cousin has his life, and you have yours. Romantically, you should do what it takes to keep them apart. You're just going to have to settle for the second hottest guy on the planet.
All assuming this wasn't a joke post of course?
