How to Cope with Unrequited Love?

A loyal reader of mine asked if I could share on the topic of unrequited love; they are coping with this situation presently, and would like some support.

Unrequited love is love that is not reciprocated or returned by the other person.  Basically, you fall in love with someone whom you can never be with for a variety of reasons.  It is really hard on the person who has these feelings for the other, especially when they think that the other person is the man/woman of their dreams.
