...so much easier to say than do it...
You are absolutely right about that. It's true of getting up in the morning, doing laundry, paying bills, lots of things.
But just as this is more difficult than any of that, this is more important than any of that, more important than your job, your credit score, even whether you eat right and exercise.
There are millions of women who remain in abusive relationships because they feel trapped. They don't have family or friends to turn to, they may live where there are no organizations to help them, or they may not know about ones that are there. Some may feel that they must remain in the relationship in order for their children to have food, others may have self-esteem issues and feel that they cannot and should not expect anything better, even that they are not worth something better.
You mention "going back next month," which suggests to me that you do have options, specifically another place to be, away from him, a place where you are safe.
Although I feel very strongly that it is inappropriate to tell people what to do, especially people one does not know on internet message boards, I make an exception for this issue.
Stay where you are. Do not go and have any talks with him. He does need to talk to someone, but that someone is a professional, not you. You have your own life to think about, and your own life is exactly what is at stake.
Many abusers who kill their victims do not actually mean to. They only mean to push or hit them, but something goes wrong, the victim may lose her balance and fall against something, the force of the push or the blow may be greater than the resilience of the victim's body.
In almost all cases, the abuser had resolved, and promised at least once, that he would never attack the victim again. Frequently within the context of a contrite and tearful apology.
If you will not consider your own life worth saving, consider his. Should he inadvertantly kill you, in a momentary lapse of forgetting his tearful and contrite and totally sincere pledge never to push you again, how do you think such an event will affect
him, and his life?
If it will make it easier for you, think of it as a responsibility that
you have to protect
him from the consequences of such an occurence.
