[ Probably not. I guess I'm just having trouble getting over the fact that she's probably gonna be getting away scot-free after what she did to me. It's like someone committing a crime but being set free due to a technicality. In this case the technicality is that if one person wants out of the relationship, its over.
You MUST get help immediately. You are WRONG about the way you are thinking about this.
Leaving someone or breaking up with them or whatever it is you think has happened is NOT A CRIME.
You CANNOT control another person to do what you want them to do. Yes, like others have said, it is hurtful and awful when someone cheats on you and leaves you. It's emotionally terrible and when children are involved, it seems like a kick-in-the-gut.
There's no technicality that she "got off" on. There's no law that stops someone from leaving. Thank goodness. If I had to stay married to my stbx-h after I found out that he had an affair, it would be a hundred times worse than it is.
It is not a crime because you do not own her. She hasn't been stolen. For better or worse, YOU picked her to be your daughter's mom. And you are still deciding to make the situation worse for your daughter by throwing these tantrums and ridiculous statements about trying to "bust" your wife for tax or assistance issues. She is not your responsibility.
She is not YOURS. Let me say it again. YOU DO NOT OWN HER.
She hasn't done anything WRONG according to the law. Get help.
