I see a lot of posts taking shots at OP. Divorce in the US is horrific to men in his position. As it stands right now at least he has a roof over his head. If he walks out today and files for divorce, it's more than likely next month his wife will be doing the same thing but with the added bonus of being able to bring her lover home to stay the night or possibly move in. Meanwhile, OP will be living his car paying for his ex wife and her boyfriends lifestyle and comfort.
