It's a sad reality that people who haven't been loved adequately in childhood are often loved inadequately in adulthood. Children tune into the messages they receive from their parents. If parents are distracted, overwhelmed by life, emotionally or financially burdened, they can't give their children the kind of attentive love and care necessary to thrive.
The "honeymoon," that sweetest time during the relationship, has fizzled. You didn't see it coming. Now you feel as if nature tricked you and you struggle to hold on to it. But it has become a lost cause and nothing you do works. You're now left with having to deal with disappointment and heartache.
If you are grieving the loss of a romantic partner or of a marriage, remind yourself that grieving eventually opens a door to new growth and happiness. I can't tell you how often I have seen divorce or romantic loss eventually, with healthy grieving, lead to healthier patterns and more fulfilling unions.
