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.
I don't know if you realize this but having sex with you when you are out on medication is rape. It's illegal and immoral in every way. His slapping you once is once too many. Are you trying to leave him? Do you plan on staying?
