Kevin, remember that they are aliens. Cool down a bit before you do or say something you will regret.
If you are fed up and are ready to file, make sure your are emotionally leveled. Don't do it on impulse. take a few days, think about it and if you are comfortqable with the possibility of it being over forever, then make your decision.
If, however, you still want to save the marriage, practice unconditional love and forgiveness. Because if you start making her life hard, she will think she is more justified in what she's doing.
Don't be a doormat and do set some boundaries. You have to do this firmly but lovingly. Remember that she's selfish and irrational right now, even if she doesn't see it.
Let your emotions stabilize a bit. Then decide how to proceed.
