Wow, this is all very sad, particularly regarding the woman who was sued for alienation of affection. It seems that is a law that should be removed, particularly when a woman didn't know a man was married.
I kind of understand the desire to "get somebody back", but the offender--not the other party. I had one very emotional break-up where I wanted to sue the other person, inform his pastor or something. Initially, we were friends for a year after the break-up, but he had a piece of jewelry of mine that he removed when he gave me a piece of jewelry. He never returned it, though I asked for it several times. When he got married a year after our break-up, I congratulated him and asked for my jewelry. He said ok, but only if I returned the diamond tennis bracelet he had bought me for a birthday. I refused and threatened to tell his pastor. His wife yelled into the phone "You give him his bracelet! You're vindictive!" Well, of course I refused to mail it to him then, and even started wearing it everyday. I wrote him a nasty letter, including my assessment of his new wife. I considered suing him for my jewelry which cost about $100, but could not be replaced; also I started to let his pastor know about all this. Thankfully, I did neither. And years later, I have no hard feelings or regrets. BTW, he and the woman split in less than a year.
The other situation (fiance) was different. Our break-up was imminent--I'd already recently called it off; then he called it off, then begged me to reconsider. I knew it couldn't work, so was about to tell him so again--right then-- when he called me and said the reason he couldn't marry me was because he had met someone else a month earlier and felt things for her he'd never felt for me, etc. But he blamed the other woman totally--she'd asked him to dance, given him her phone number, asked for his, asked his family about him constantly and for them to tell him hello, etc., etc. Anyway, we agreed to mutually break-up. A few months later, I learned that he'd married this woman exactly a month after we'd broken up and one day after our last communication. He did so secretly, hid it from people. I was furious--I was ok with our break-up, as it was mutual, but felt like his pastor needed to know what kind of man he was. {His church was close-knit and involved in the members' lives.} I wrote a letter to his pastor, but kept it on my computer, without printing and mailing it. Finally, I erased it. I am so happy I did. Also, I learned that he'd left that church immediately after our final break-up and upon pursuing this woman. I am so thankful that I didn't marry this cad. I could've sued him for one particular financial situation, but it definitely would not have been worth my time, self-esteem, etc. In any event, I would never have done anything to this woman, whether or not she came on to him first--she was an opportunist and they deserve each other.
