The pain inflicted by the people we love often isn’t intentional but it happens. It takes a very strong love to continue to love someone even after we’ve been hurt by people in the past, but real love is always worth it.
Like everything in life we are going to experience ups and downs in our relationships. The only type of advice that should be received in relation to your own personal relationships with loved ones is to make sure that you are being courageous in them. Real love can not be present with an absence of courage.
