"Never be ashamed of the scars that life has left you with. A scar means the hurt is over, the wound is closed, you endured the pain and God has healed you." Need to remember this for my psych patients
Forgive others not because they deserve forgiveness, but because you deserve peace. maintaining resentment only hurts myself I can avoid the injurer, but I don't need to harbor resentment and hate and ill will; those things only damage my own psyche.
You don't need another human being to make your life complete, but let's be honest. Having your wounds kissed by someone who doesn't see them as disasters in your soul but cracks to put their live into is the most calming thing in the world.
