My husband asserts his exclusive love for me but wishes to marry another woman without justification. I disagree with this marriage; does my consent matter? Given my inability to handle the stress of a second marriage, am I allowed to ask for a divorce?
Bismihi ta'ala
Your husband should concentrate his focus on you, and not aim at pursuing his lust. He should focus on building a family with you, and living a prosperous and productive life. You have a right to object, and you also have a right to ask for divorce. That will be your choice and your choice only.
And Allah knows best
