Everything that YOU have done, even if in error, has been done in an effort to PRESERVE your marriage.
Everything that SHE has done, has been done to FLEE from her marriage, and to cheat.
Doesn't make you a saint -- you both are still responsible for your own issues in the marriage -- but there's simply no comparison between the tactics and actions of the two spouses at this stage of the game. One is done from a position of morality and ethics, and the other from a position of fantasy, escape, entitlement and lust.
