I had a falling out with my friend at work and now I hate her, what should I do? (Story included!)?

wow,thats a shame. I've recently found myself in similar situations as this. When you go out of your way to help someone, and share and give to that person only to be unappreciated and worse, betrayed, you are left with nothing but anger. #1 learn from this. Dont let your self be taken advantage of again. There were alot of red flags that indicated you were being used/taken for granted. Now, avoid the girl/talking to or about her and just hope to move on without confrontation. If you find yourself in a confrontational situation, just keep your cool. These events leading to the blowout seem to span over months, and your likely to have totally different accounts of what actually happened. since you have no blood ties to the woman, there is no need to go into that heap of a mess unless you are trying to make her feel remorse. which y would you care how she feels if you dont plan on continuing a friendship w her anyway?
