My female friend had a man that harassed her physically and she moved out to her friend and said to him that she will separate from him if he continues to do that, etc., etc., but then she returned back and he has not been as half as violent since then because he had fear to lose her. Try it. But you must decide in yourself that you can live without him. You must decide that in your heart and he will feel it, he will really feel that you mean it. But to do that you should ask God to help you. The problem is that this woman has been sexually harassed by her uncle, etc., etc., and she developed that feeling of neediness for love and desire to please a man only to confirm herself, that she is worthy of love. It was deeply rooted, but as she grew in God, she realized that she has made an idol of her man and that she trusted in him and relied on him more than she relied on God and that was a big wake-up call for her. She stood up for herself and things changed. It is interesting that her man a couple of years after that died from illness and I think it is a punishment for the thing that he attacked a woman of God (touch not my anointed, do my prophets no harm).
Pray for yourself HEALING OF THE HEART, SPIRIT OF WISDOM AND REVELATION, INSIGHT of how God sees you and how God sees him, ask for scriptures for your case and stand on them. Our fight is not in flesh and blood but with the spirit of God. Cut off all soulish ties to your man that are unhealthy (I cut off now all unhealthy emotional/soulish ties to my man, in Jesus name!). Cling to God like never before. Your God should be your spouse to you, first and foremost, no other man should be standing in that place, your man should be in the second place always.
It is possible that you have some kind of calling on your life and the devil wants to destroy you through your spouse. Spirit of Jezebel can obsess even a man (Jezebel was a female in the Bible). This spirit wants to destroy Holy Spirit and everybody who are called to serve God deeper. Your only way to paralyze that spirit is that you must be subject to the Holy Spirit and then you can beat that evil spirit. And you can do that only by prayer, praising GOD, reading the Bible, asking guidance and revelation. That spirit manifests often like a manipulator, liar, threatening, harassment (verbal, physical, emotional). I dealt with that spirit through my mother.
Your man should not be your first choice, your first choice is God, when you do that, things will start to work in your favor. Dependence on your God, not on your man. And you should do that first and foremost with spiritual fight.
God bless you.
