I saw this chick on Dr. Phil. Kristen said she has no idea who is doing this and why. Dr. Phil was able to find out one clue about the string leader, the person is male. Kristen if you are still coming here, here are my feeling on this matter: I have a feeling this is someone you know. Some one you made angry, without knowing you made angry. Most likely someone you said "no" to sex to, and this person is insulted and angry now. When you said "no" it may have been outright or in a 'indirect' manner. Either way this person got the hint and is not happy. I know this is upsetting to you, but if you calm down and think about it this person will come to you. I suggest you read the book "The Gift of Fear" by Gavin de Becker.
I am so sorry this person is so mean. He just did not get what he wanted. You be strong. You can do it.
Good work Morgan.... Kristen is a wonderful attractive woman and needs to be left alone, the person doing this needs to leave her alone and let her get on with her life.
