Goodbye, my friend...for now.
As of today, you will no longer have a part of me. I think I've done my share (and more) as a good friend. Your lackadaisal/passive attitude towards our friendship has made me realise that I am tired; I no longer have the capacity to deal with the emotional roulette that you put me through.
I wish I didn't care so much. It causes me too much heartache. Maybe you think I've been too pushy. Maybe I no longer count in your list of priorities and you are no longer interested in maintaining the same level of friendship that I want with you. That's all fine. Choices are made solely by the individual.
Therefore, I say this: I am taking a step back. You decide what the next step will be.
p/s: This is NOT a personal attack. If you think this is about YOU, then sit back and think about it before you get on your high horse and launch your defence against this entry. If you know in your heart, you are guilty of this, then do something about it. If not, I'll know the answer anyway.
Remember: If your heart is clear, you should have no fear.
