Welcome ... I'm sorry to hear that you are in such a difficult situation.
I highly recommend that you read the following article by LadyLee: Til death do us part - divorce
The main point of the article is that marriage vows to "love, honour and cherish - in sickness and in health" have been broken the instant one partner begins to abuse the other. Spousal abuse is just as serious a breach of those vows as infidelity.
You have a right to not be abused. Spousal abuse is illegal and grounds for separation and divorce.
Even the Bible admonishes that one partner can depart if the marriage is not working out - and that includes for serious violations of the law like spousal abuse. The WTS has published information to this effect also.
*** Rbi8 1 Corinthians 7:10-15 ***
10 To the married people I give instructions, yet not I but the Lord, that a wife should not depart from her husband; 11 but if she should actually depart, let her remain unmarried or else make up again with her husband; and a husband should not leave his wife.
12 But to the others I say, yes, I, not the Lord: If any brother has an unbelieving wife, and yet she is agreeable to dwelling with him, let him not leave her; 13 and a woman who has an unbelieving husband, and yet he is agreeable to dwelling with her, let her not leave her husband. 14 For the unbelieving husband is sanctified in relation to [his] wife, and the unbelieving wife is sanctified in relation to the brother; otherwise, YOUR children would really be unclean, but now they are holy. 15 But if the unbelieving one proceeds to depart, let him depart; a brother or a sister is not in servitude under such circumstances, but God has called YOU to peace.
Can a man who abuses his wife really be "a believer"? How does his abuse line up with the scriptural instructions to "love his wife as himself" or "cherishing" as both the Bible instructs and the vows he spoke before God?
The elders have no business ordering you to stay in an abusive relationship. They aren't living your life. You are. You deserve to be loved, cherished, respected, and safe. If you aren't, you need to make a plan and get some support systems in place and get yourself out. The elders may DF you. Your husband may tell them that you left him for another man. They'll believe him, despite your many requests for help to them to require him to stop abusing you. Whatever happens, it is not your fault. Remember what that scripture says: God has called you to peace. Go ahead and find it. You owe it to yourself. Nobody can look out for your interests better than you can.
I hope you can someday find the strength to not take that crap anymore. You deserve better.
