Dont listen to all these assholes that tell you to hang in there and do it for the kids. Your bitch whore wife will ruin you, she will always have the advantage (especially with kids), and it will never get better. Why f'ing stay here? you tried to do what you're supposed to do, regardless who is more to blame (I'm sure you're not perfect) it didnt work, and now there isnt anything you are going to do to make it better and your wasting your life so she canlive in your stupid suburb, drive here oversized SUV, and go to the mall so she can be like everyone else.
I personally would leave and move out of the country and becaome an ex-pat somewhere (somewhere where they cant garnish you're wages because she will come after you). I would definetly make sure all your obligations to the federal government are taken care of (fed taxes and stuff so you can re-enter the country w/o federal agents waiting for you and only the feds will try to extridite you). Also, if you do it DO NOT stay here, all you will do eventually end up in the same situation, dude, you gave it a shot it didnt work, get out and live your life.
Unfortunately your wife will control the kids untill they are adults and she will make you out to be a villian, there is no way around this. It sucks for the kids but at least down the road you may be able to face them as a man instead of the f'd up loser this life makes us.
good luck, and all you fat fucked up golf playing suburb living pharmaceutical rep bitches shut the fuck up and do what you cow face wife tells you to.
