How does Shakespeare present Romeo before he meets Juliet?

Romeo is presented as a Petrarchan lover. He does not seem to truly be in love, he idolizes Rosaline and puts her on a pedestal. He appears to be in love with the idea of love rather than actually being in love, it is an infatuation.
Firstly, the language that Romeo uses makes the audience suspicious of his love. He uses quite conceit and exaggerate metaphors making it appear as though he is putting on a show. He likes the idea of being in love and, as he is young, he might not have experience true love before. The language he uses seems quite artificial and elaborate. This reinforces the idea that he is in really in love. Also midway through a speech about his love and Rosaline, his mind seems to wonder as he asks “where shall we dine?” this shows that he is thinking about food and not only about Rosaline.
In addition to this his use of oxymorons such as, cold fire and sick health, makes his love seem quite stylized. Along with this, he speaks in rhyming couplets when talking about Rosaline in some points. This again makes it seem quite unnatural and as though he had thought it before. When he talks about Rosaline it seems as though he is acting the part of an unrequited lover. We notice this, along with Benvolio, which makes his love almost comical as we know that it is not serious. Also he often says “O” with a sign. This makes the audience feel that he is being melodramatic. This expression of anguish seems over the top. This again reinforces the idea that his love is false.
Similarly, as Benvolio is close to him we trust what he says. It comes across that Benvolio does not believe that Romeo is truly in love. He laughs when Romeo is being over dramatic. When he says “No, coz, I rather weep” in reply to Romeo asking if he laughed, It appears to be almost sarcastic as he is trying not to laugh. This makes the audience think that, because Benvolio seems to agree, our view is right as if someone close to him believes this, there is a high chance it will be true.
Likewise, the way that Romeo acts seems quite far-fetched. He seems to wallow in his misery and enjoy his sadness. For example, Capulet says his son goes home and sits on his own in his bedroom in the dark. This seems to be quite extreme. He only goes out before dawn then comes back to be on his own, it makes the audience think that he pities himself. He wants to be alone and runs away from his friends. When he says “Ay me, sad hours seem long.” This again reinforces the idea that he is self-pitying and wallowing in his sadness.
Romeo could have been presented in this way so that his love for Rosaline does not seem true. This means that when he meets Juliet, he is really in love and that he had not felt love before he met her.
