However, you are NOT the bad guy in this. You shouldn't for one second make yourself think that you are. He is the one who started all of this so everything that transpires thereafter is because of his choices. If you feel that you want out, it's not because you are doing anything wrong - it's because of things that HE did wrong. I hate to think that anyone would beat themselves up over the other spouse cheating, kwim? Even if he doesn't choose to work things out, I think you should see a professional to work out your feelings. You and your children deserve the best.
