If two past lovers can remain friends, it's either they are still in love, or never were.

One reason that we should always be careful who we love is because of the fact
that everyone that we give a part of ourselves too is a person that we ultimately
take a part of and fill our own spirit with as well. Whether or not the relationship
we have with the people that we truly love is able to work out or not, the people
that we give our love too will always be a part of us. Sometimes falling in love
happens way too fast and we have no control over the feelings that we may incur
for a person way before we are able to clearly think things out. Love, when done
right, is one of the grandest gifts that a person can share with another person.
Yet when love fails, it can bring out the worst in emotions and the worst in pain
that a person may ever endure. So be sure to guard your heart until it tells you
that the time is right to let go, and when it does, love hard!
