“Women in particular typically “tend and befriend” others, as an evolved survival mechanism. If women are unable to maintain a relationship or friendship, they may feel disappointed in themselves, not just their partners or friends. The inability to keep a relationship on track, even if the other person is to blame, can be perceived as a personal failure.
Eventually, the loss will begin to feel more like your history, not your present. In fact, research suggests that relationships that are unsatisfying or marred with unpleasant interactions are worse for your emotional well-being than an absence of romance or friendships.”
