Answer
As-Salaamu ‘alaikum wa Rahmatullahi wa Barakatuhu,
SubhanAllah! When two people make a contract with one another and one person in that contract breaks the contract, that contract become null and void for the other person in the contract! If you husband swore as you say he did, and still took another wife, you should not want to be with him because he has little to no fear of breaking his oaths to Allah and the seriousness of his oaths to Allah! A woman’s—wife’s—only protection in a marriage is her husband’s taqwa (awareness of Allah watching him and fear of doing wrong and displeasing Allah).
A man is not supposed to obey his wife, so he is supposed to do right by her not because she said to but because Allah told him to, and that is the very thing that your husband is not doing!
Please double check with the scholars on this site if what I have told you is true – that you can break the oath you swore because he broke the contract first, so you no longer are obliged to keep your part of the contract. Also, contracts that are not Islamic are not binding and your contract sounds really iffy. Please ask a scholar about these finer details of fiqh!
I want to compliment you on your taqwa, may Allah increase you in good and in reward!
If you have to keep your word/contract and live a future life of celibacy, in the Quran, Allah says that, when we are traumatized, or very scared, or extremely sad, or the like, we should deal with it by saying “inna li lahi wa inna ilaihi ra jee un” (From Allah we come and to Allah we will return). Thikering this helps the believer see life in its true context, as part of the whole of it, which includes the next life too. That one short sentence references the beginning and the end of life, thereby referencing the essence of life, that life is for the next, not this one.
May Allah Make it easy for you.
