CONCLUSION A
YOU ARE BEING USED....
You have a really big decision to make. You are really too nice for your own good, and your "friends" know that. They seem to think that they can use you just because you're not going to do anything about it. The chances are, you have noticed this, but they are right, you can't stand up for yourself. If you feel that you should do something about it, then go ahead and take the bull by the horns - confront them. If they decide that they don't want to be "friends" with you anymore, then maybe they didn't deserve to be your friends in the first place.
