[Serious]Do you have or have you ever had an archenemy and was it a mutual rivalry?

I went to a martial art school before this family joined, lets called them family x. I had been at the school almost 2 years and their now highest ranked female bjj student and longest running female kick boxer. The school has only been open 4 years by then. Family X had their daughter and the father training. The mother was on the side lines. This would be now the daughters 2nd or 3rd different martial arts school. Mother claimed the daughter was being bullied at school, turns out it was the truth, the daughter was being bullied because her mother was bulling the other mothers or causing a load of shit. My nephews also attend the classes, one is in the adults class and one in the kids class along with daughter x. My nephews go to a boys school and daughter x attends the girls school next door. My younger newphew develops a little crush on daughter x, mother finds out and isn't happy, their 12 year old kids ffs. Anyway both of them get put up to the adults class, as there was no teens class. One day older nephew squeezes daughters x handed as we end the class in hand shakes, my nephews is a dickhead but he meant no harm and was just joking. I send my older nephew to get him and his bother something to eat while i do the kick boxing class, she sees him, mind you he's 13 and she's 36. She gets into his face and challenges him to a fight. I didn't find out this until after the weekend. On the weekend UFC was in town, i went with my friends and family x went too. Family x see the assistant coach and mother x tells him that my nephew confronted her and my younger nephews was harassing my best friends kids. She's twisted everything. Come monday my nephew is warned he's about to get kicked out. I find out what really happened, and send an email to one of the coaches who owns the gym and tell him my side, i always tell the turth even if it makes me look bad. I tell him my nephews are not to go anywhere near family x especially the daughter because I'm afraid of sexual harassment allegations later. Father trys to make peace i tell him to nick off. Come October, my best friends kid is competing against a girl family x knows. Father X helps coach the girl against his own team mate. So i took to facebook and told what happened. I added some shit about his daughyer beinf pushed to wrestle grown men instead of women in the club and kids her size. This i regretted. Anyway shit hit the roof, father calls somebody who had nothing to do with it other than to agree with me and treatens to bash him. They wanted me to apologize, i apologized to their dauggter and that was that for me. I owed her parents nothing. Well we all got suspended for 2 months. I go to the gym and drop off my newphew and wait for him on the stairs outside the gym as I'm not allowed in for 2 months. No biggie for me. Family ex come in see me and mother and father go ape shit. I say nothing and just let them dig their own graves, i almost went to the police though due to his intimidation. They cancel their membership. Place was never the same for me again i canceled 18 months later and went to another bjj school well away from the area. They went to another school a year later they left that school too and went to another. It's alleged the mother made sexual advances to the coach who was married too. It's been over 3 years and i still want to smash the mothers face. I hate her more than i hate my ex. I honestly feel sorry for her kids.
