Theft, slander, and defimation of character

Know for the slander and defemation of character question. I have been talking online to the girl that slept with my husband. She knew he was married and knew we were having problems and still slept with him. At first I felt sorry for her cuz I thought she didn't know he was married, but when she told me she knew my feelings toward her obviously changed. She tried to claim that she's not a slut. Unfortunately I got angry with her and called her a slut. Now her fiance is trying to threaten me and my husband saying that they can suit us for slander and defemation of character. Is this possible?

side note: My husband has not once called her names, but they continue to call me bitch and my husband horrible names.

It sounds to me like a tangled web of infidelity whereas you all need to get on with your lives and focus on nuturing the current relationships that you have. I'm not an attorney but as for the threat of your being sued for slander, I don't think it would hold up in court. If that were the matter, every time there was a cat fight about men and names were called, there'd be millions of lawsuits.

You chose to become entangled in conversations with this woman, I'm sure to find out more about what happened. Your focus instead should be in your communications with your husband. Her focus should be in her communications with her fiance.

Your husband was wrong to sleep with her, being married to you. She was wrong to sleep with him when she has a fiance. The bickering over she did, he did, she said, he said needs to end and you all need to move on to try to mend your immediate relationships.
