Frankly, your examples are lame at best. I have a real live example for you guys to discuss.
Recently, I have a really really really good friend who committed suicide because of a girl. She started out dating him but never slept with him. As soon as they moved in with each other, she quit her job. She then went to college, all of which paid for by him of course. Eventually, all his pay checks went straight to her. Many of us saw the manipulation from the beginning. We really began to beg him to realize that he'd been manipulated by this woman. Somehow, she got him to stop talking to his family, friends, and work mates. Right before he committed suicide, I was the only person left that he was willing to talk to.
After his suicide, I was told by the investigators that that woman had cleaned out his bank account and repeatedly called survivor's benefits (he was a cop by the way). Fortunately, even though he told her he put her as his beneficiary, he actually put his mom down for it. She continued to call beneficiaries for the next couple weeks before she stopped.
She came to the funeral with a couple of her girl friends and they laughed while the family were crying. The local police department had to ask them to leave.
After the fact and everything had calmed down, I did a little digging and lo and behold my friend was not the first person to have been manipulated to give her everything and committed suicide. There was a guy down south that she met when she was 16 who gave her everything he had and then killed himself. The fact that she showed up at my friend's funeral and laughed tells me she took pride in driving men crazy to the point of suicide. Somehow, I suspect that she will soon seek out another potential victim for her manipulation.
Since that time, my friend's family and I have been trying to seek a legal mean to stop her from doing this to someone else. Unfortunately, there just isn't a legal mean to stop her. It's not illegal to manipulate someone like that. It's not illegal to drive someone crazy and then put the gun in his hand.
When justice fails, what do we do? Do we simply stand by and watch this woman continue to find other men who will give her everything they have and then kill themselves?
