If its a circle...When will I get hurt again?

No matter how hard you try, you get hurt. No matter how honest you are, you get called a liar. When you would give up everything for one person, and they shut you down and say that you're a player. When they break your heart then go for your best friend. When your best friend goes for him and it destroys your friendship. When you feel as if you have no one. Out of the blue, your friend wants you back. The guy you once loved and would give anything for, wants to talk again. You hangout with one, hear about things. Ask the other, they deny what happened. Decide that you are sick of the crap and forgive them both. When?? When will I get hurt again? If this is a circle, how long will it take before I get everything taken from me once again? Did he really care for her or do it to get under my skin? Do I distance myself or do I let things go back to the way they were? These are the type of things I deal with and try to make sense of everyday. I stress and worry about these things, wonder and ask myself what I should do. I try to go day by day but it gets harder. I don't want to screw up...and most of all I don't want to get hurt again.
