No one that truly cares about how you feel will make excuses for bad behavior. People that make excuses for bad behavior want you to lower your expectations/standards you set for yourself on how to be treated so they don’t have to live up to those standards. A person that truly cares about you apologizes & takes on the challenge to be a better person. The person won’t even let fear / the belief that he or she lacks capability to get in the way to becoming a better person.
