This is definitely abuse....in many forms. You are in a very dangerous situation. A man who feels he can control you, what you do, what you wear and how you act will also give you absolutely no respect, love, appreciation or happiness. He obviously feels he is inferior to you and has every right to control you. That is dangerous enough without adding the violence in. One day he won't be punching the wall.
The threat of suicide is a big red flag! He is using this as emotional manipulation to keep you in the relationship and make you feel guilty for leaving even though he is the cause of the break. The fact that he has threatened you with this also magnifies his violent nature and could possibly cause him to harm or kill you as well as himself. Severe emotional issues. Get out before it gets worse. If you think he will hurt you get help and learn how to protect yourself. Taking self defense classes and getting pepper spray or learning how to shoot a gun are never wasted efforts. Better to be safe the sorry.
