To have friends, you must show yourself friendly.
I believe this with my whole heart and I do my best to uphold this tenant in my life. But much like my issue with The Golden Rule, I have been struggling with why I should continue to be friendly to one who clearly ISN'T being friendly.
Frankly, I don't see the need at all.
Over the past 3 years my life has been reshaped and bears little resemblance to the life I had before those changes. During tough times, one learns who are genuine friends and sees more clearly those who are of the fair-weather variety. Those are the times it is difficult to know when one should continue to show friendliness and when one should look at the lack of friendliness which has (or hasn't in this case) been extended and decide to cut one's losses and simply walk away.
I have learned one very important lesson through all the changes and finally walking away from the Unavailables. I don't need any boomerangs in my life.
To the longtime friend who chose to show herself "friendly" by deleting and blocking me on Facebook without anything bad transpiring between us: I will consider this your way of telling me you no longer want to be friends. I wish you well and thank you for deleting me so I don't have to waste any more effort than this blog.
And that's all I have to say about that.
