How does the lack of communication contributed to Romeo and Juliets death

Romantic love and passion seem to cancel out any communication in this play. Romeo and Juliet get married in secret. Most of other characters seem to orbit around this secret unaware of the union. They go about life, their family feud, their petty grievances without actually talking about anything substantial. Even outr two protagonists fail to communicate about anything beyond love and sexual innuendo. Even the Friar is unable to communicate his plan effectively so things go wrong.
