Ranting on Ridiculous Ultimatums

For the third time in as many months, I have had someone try to screw me over, twice by one person. I'm not really sure what it is about me that attracts these kind of people. Maybe I look like a pushover or too timid, I don't really know but it's infuriating. In all situations, an agreement was reached between all parties. Then the person decided that she changed her mind and really doesn't want to do what was agreed upon. She then comes up with what she deems "fair" without consulting anyone else, and then basically hands it down as an ultimatum to me. No compromising, no negotiations, her way or else. I'm not sure how these people learned how to solve conflicts, but especially if you are the one who is backing out on your word, you better be prepared to offer something in return. If you are the one going against an agreement, shouldn't you be the one to compromise a little more than the other party? At least that seems like it makes sense to me, but I guess not to other people.

I guess this might be a case of "fool me once, shame on you, fool me twice shame on me" because this is the second time on of these girls has pulled this kind of ridiculous bullshit on me. But I considered her a friend, and since things ended up working out really well for all parties involved, I decided to give her the benefit of the doubt and drop the issue. But this time it has happened again, and in a more serious manner. And the easy solution would be to explain how this was not ok and why I am so angry about how she handled the argument, but the problem is that we will have to see each other often and there's really no getting around that. But it's hard not to be disgusted with the selfish, childish behavior that is becoming repetitive nature to her.

So needless to say I guess I'm just hot and bothered and ranting to no one, but dealing with people who think it's ok to treat others this way is mind boggling. I never knew that to some, the idea of negotiation and compromise meant one person opens with what their "bottom line" is and that they will not move away from it, and expect everyone else to just succumb to these demands. My only hope is that after a month of cooling off for everyone after this last incident, we can at the very least start to maintain some civility, because I think friendship at this point may be out the window. Getting stomped all over is not part of my game plan for this year, and whether I lose some "friends" in the process, so be it.
