You have to be capable of sticking to the boundary . Don’t set a boundary that you can’t uphold . If you are still being intimate with her knowing she is with AP that is for you to decide the boundary . The boundary is for you not her . Your well being . The more you set one the more she may test it . If you want the boundary that you have no place in your life to discuss AP set it . A simple I understand you want to talk about AP but I will not . If AP is brought up stick to it . Kindly but to the point . GAL more and more and more . She may get upset at your GAL but keep pushing toward . The stronger you become the better for you .
