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.
That question does not have to be answered to us. If I were you it may make an impact on my decision whether or not to take him back.

It's all up to what you want and feel is the right thing to do.
I wish you the best
