What does Friar Laurence mean by saying Romeo is wedded to calamity?

By saying "Romeo is wedded to calamity," Friar Laurence means that Romeo's bad luck and misfortune seem to follow him wherever he goes and that tragedy seems to be his constant companion. This is evident from the series of unfortunate events that have recently occurred in Romeo's life, including his estrangement from his family, his failed attempt to crash the Capulet ball, his banishment from Verona, and his involvement in the death of Tybalt. Friar Laurence believes that Romeo is somehow cursed or fated to suffer and that no matter what he does, he cannot escape his tragic destiny.
