Why did she give you a week? is it 5 days or 7?
Is this her typical response or tactic when caught or embarrassed to become aggressive?
Why does she have to keep doing this with your friends? What kind of friends do you have that would trade that for romp in the rack. Are any of these guys married and in open relationships?
I think you need a new (different ) wife/ partner and a better class of friends. It looks from the outside that you're being played as the chump...and she clearly doesn't understand that everything she's done and CONTINUES to do makes trust difficult. Its earned ....NOT given.
