Answer:
Friar Laurence believes that Romeo is merely in love with the idea of being in love. Friar Laurence feels Romeo's love is motivated by his physical appearance rather than his feelings. Friar Laurence is concerned about Romeo's sudden emotional shift from one woman to another. He is concerned that such irregular behavior indicates physical desire rather than deep-seated love, which is also wrong. Nonetheless, he chooses to marry the young lovers out of love for Romeo and a desire to put an end to the animosity between the two families.
