opinions on Romeos character

I think that Romeo is just in love with the idea of love. I believe this because in act one scene one Romeo says depressing stuff like he is so sad because Rosaline doesn’t want to get with him and that his life is over but once he saw Juliet he says that he is so in love even though he just saw her. To make my point clearer he goes from one girl to another in like a matter of minutes. For example when he saw Juliet for the first time he says stuff like “oh, torches look dim beside her! She embellishes night like a rich jewel in an Ethiopian’s ear-too beautiful for everyday use, too valuable for this world. She stands out like a snow-white dove among the crows. Once the dance is over, I’ll see where she stands and make my rough hand blessed by toughing hers. Did my heart know real love till now? My eyes need look no further: I hadn’t see true beauty till tonight.” Even though just a few hours ago he was going on about how beautiful Rosaline is.  Another thing is he will do just about anything too keep this love that he so desires, he would even spit on his families name . He expresses this claim when he hears Juliet complain about how she wishes he was not a montague and he said” I don’t like to use my name to tell you who I am. My name, dear saint, is hateful to me because it’s an enemy of yours. If It were written, I’d tear it up.
