Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
Think about it. What could he do to you that would justify treating him like crap? You wouldn't. You just wouldn't treat him that way because it's not an appropriate way to treat someone.
And on top of that, how much of your depression was CAUSED by his treatment of you? By the fact that he dangled your dream in front of you, then took it for himself and left you to work 2 jobs to support his theft of your dream?
You never deserved to be treated badly, even if everything he said about you and his ex was true (which it no doubt was not).
