I think what others have said here makes a lot of sense and Laneba if you don't listen to them listen to your own insights,you know that this relationship is abusive and that it is bad for you that it is toxic,in your own words.Ok the initial attraction was intense and he has promised to change and that things will be different,they won't,you might as well jump into a blazing fire and destroy yourself as you will be going back to his constant anger and picking on you,belittling you and controlling you.
I think you need to ask yourself before you go back to him,is he a narcissist?
Google the term,explore what it is you are actually dealing with and understand his promises will amount to nothing.
