Oh doesn't it hurt to watch our AC suffer?
We cannot take their pain away but we can be supportive, and sometimes opening up conversations about how they're feeling can be helpful. Mine tended to suffer in silence, licking their wounds quietly. All my adult children have hurt badly when long term relationships ended. It hurts us too, as their partners were, for years, part of the family.
I know one of my children has avowed to shun relationships as he was left completely wrecked when his partner ended it after eight years. It left him without self esteem and so badly hurt. A period of deep depression followed and he has 'sort of' recovered. I don't think the wounds have healed. Despite all his talents and skills, he ploughs a lonely furrow. All I want to do is hug him, and find a nice girl who won't hurt him.
We cannot mend their relationships though, can we, and the old adage that time is a great healer is true. I am over my ex husband now but 20+ years later, deep down inside, that pain and betrayal still has the power to hurt and have me asking "why?"questions.
Knickas, I am sending thoughts your way. If our children are unhappy, no matter their age, it hurts us too. People move on, and we have to let them, but I do hope your daughter recovers, slowly. She will, and she will move on, and I hope in time, find someone who will love and cherish her.
