Romeo has been hiding out at Friar Laurence's cell, consumed by grief and guilt over killing Tybalt. He is behaving recklessly and impulsively, torn between his love for Juliet and his loyalty to his family. When he appears, he is tormented by the conflict between his desire for peace and his need for revenge.
Romeo is a young man from the noble house of Montague. He has been behaving moodily and appearing melancholic. When he appears in Act 1, Scene 1, he is bothered by the unrequited love he feels towards Rosaline, who has sworn to remain chaste and not return his affections. This unrequited love is causing him inner turmoil and distress.
He Misses Juliet
Lord Capulet let romeo stay at the party because he did not want an uprising to make him look bad at his own party. Trust me I read Romeo and Juliet 3 and a half weeks ago.
Romeo appears to change his mind on a whim.
Everyone in the play appears to be Roman Catholic. What Romeo's views on that are, we are not told.
The phrase "a right Romeo" does not appear in Romeo and Juliet. The phrase is used elsewhere in the UK English idiom of "a right [noun]" -- that is to say, "something in keeping with [noun]." To call something "a right Romeo" is to say it is "behaving in a way typical of Romeo"; generally, to be disposed toward romantic love.

Tybalt recognizes Romeo and becomes angry that he is at the banquet, as he is a Montague and they are enemies of the Capulets. However, Tybalt is restrained by Lord Capulet, who orders him to leave Romeo alone because he is behaving courteously.
Romeo compares Juliet to an angel who stands over the clouds.
In Act I Scene 5 Tybalt tells Capulet that Romeo, a Montague, has crashed the party. Capulet tells Tybalt not to bother about it: Romeo has a good reputation, and is behaving himself, so why disturb the party at which everyone is having a great time?
We are not told much, but at the start many of the characters (e.g. his parents, friends) notice him to be behaving antisocially. Although, Capulet says at the party to Tybalt that Romeo is known to be a 'virtuous well governed youth'.
