Hold your head up high and act "as if" show them you are a classy lady that doesnt have to go out and take another woman's husband and one that does not give it a second thought that she has destroyed a family unit.Don't give her anymore space in your head than she has already....look good, smell good, there is no better revenge than to act like she is nothing to you.....after all look at her prize.....a liar,a cheater,a coward,a man who couldn't do what was the right thing to do,not do what felt good....just my thoughts and I am sure easier said than done...good luck....
