Love someone who is in love with someone else?
This is a very unpleasant place to be. Believe me you are not
alone. This has happened to literally millions of people who may or
may not be like you. So try not to feel to alone in this
As painful as this is, let them go. Do yourself a favor and try
to move on as soon as possible. Do what you need to do in order to
deal with the emotions of letting go. Once you have done this you
will feel alot better.
This may not sound like much, but you have choices to make, and
I am sure you will make the right choice for yourself.
