Nothing wrong with feeling resentment toward the woman who is taking your husband from you. Resentment is normal.

She owes you no loyalty. But leaving a married man alone is not "loyalty." It's decency, and she obviously has none. Same with my wife, BTW....

Go ahead.... be angry with her. IMO, no need to "work through" this, unless you have designs on revenge...
