Romeo Internal Conflict
One should not act rashly before thinking.
Act II, Scene 3
Friar Lawrence is telling Romeo that he isn't thinking the love he gained through, and Romeo is going too quickly.
The Friar is warning Romeo to slow down and not rush into his love, due to the fact that Romeo and Juliet had just met.
Act I, Scene 5
Romeo is upset that Juliet is a Capulet. After knowing that Juliet is a Capulet, Romeo still decided to be with her, even though their families are mortal enemies. This is a show of him either loving Juliet a lot (they just met), or him not thinking this through.
