Wow, i didn't expect that amount of backlash! Although I know how much mumsnet can be judgy.
For those who have said I am smug, I really am not. I did not steal anyone's husband - he left of his own accord, as i left my husband. Ok, we were wrong to cheat, which is why we ended up leaving. We both knew, for separate reasons that our marriages were over.
For the record i was more than 'happy to take one on the chin' as posters have put it, which is why i came to the door in the first place. She had every right to confront me. However it was my exh that called the police, he does not condone violence and was actually quite worried as she was damaging our property. Once the police turned up and they saw the damage she had caused they have a duty to the public to arrest and charge. Once we had given a statement it was all out of our hands.
She lost her job as her employer did not want someone with a criminal record working there.
My point was purely that every action has a reaction so to speak. As far as my exh was concerned him telling OM's wife seemed like a good idea at the time, but due to her reactions it didn't fair too well for her in the end.
People do have to take responsibility for there own actions. Fracturing someone's cheekbone and putting a hole in someone's door is illegal, regardless of the motive.
