Romeo is an extremist towards love and his love is over exaggurated. Points to prove this is that he is first incredibly in love with a woman named Rosaline, someone who isn't even aware of his existance. He denies he'll ever get past her love, even creates a conflict because he is that sure that she's the one. He notices Juliet and is in love only from first sight. He's inlove so much that he forgets the woman he's been incredibly in love with till that moment.
The love towards Rosaline is a little to extreme. Romeo loves her like no other. He describes his love towards Rosaline being very strong even though he knows he cannot have her because she will not marry :
Alas, that love, whose view is muffled still,
Should without eyes, see pathways to his will!
Where shall we dine? O me! What fray was here?

Dost thou not laugh?
I.i. 168-179

Romeo is an extremist towards love because he stays in love with this woman he cannot have and who also causes him much pain. He doesn't even feel like himself : "Tut, I have lost myself; I am not here/ This is not Romeo; he's some other where" (I.i. 194-195) but he still loves her and even creates conflict when someone tries to point out how he shouldn't be inlove. Romeos' friend Benvolio gave him advice by telling him to examine...
