There's good advice in this thread, and I agree: you are acting selfish and dishonestly, so I won't repeat it.
But if you think that she's treating you poorly now, you might want to take a moment and hope she doesn't get a good lawyer who will be sure to show you exactly how much pain you have caused your family.
Beyond just the emotional and physical betrayal you did by being inside of another woman, you literally put their lives at risk for diseases (unless you had your lover take a blood test and you took one too before engaging in your infidelity).
I thought it was bad enough that I had to get blood tests for over a year to ensure the ex's tryst didn't give me HIV, a friend's lawyer did one better.
As part of the separation & divorce settlement, not only did the husband have to go with his spouse each month to get a blood test, he also had to go with his kids to the doctor's office every month for them to be tested for STDs (for example, hepatitis can be transferred after drinking after someone).
So he had to watch his kids cry and get blood drawn (or other tests) and know he was the reason he was there. That might sound brutal, but d@mn if it's not genius.
