I Built Him Up And Now He Wants To Leave Me For Another Wife

I need an advice on a situation that is breaking my heart. It’s been only six months since my husband and I got married, and he is already asking to bring a second wife into our home.
I’m 35, and he is 29. He knew about our age difference before we even started dating, and while I had some concerns, he always told me that age is just a number. We dated for a year and then got married in August last year.
Now, just six months into our marriage, he is telling me that he doesn’t find me attractive anymore and wants to take on another wife. I’m two months pregnant, and this is what he wants to do to me? I don’t want to boast, but I’ve done so much for this man.
When we met in 2021, he was unemployed. He is fluent in English and intelligent, but only has a secondary school education.
He was working at a private school but quit to start a business. Unfortunately, he lost all his capital to criminals. I decided to help him, thinking he was a good man.
I supported him, offered him a salary to supervise a few of my businesses. I own four supermarkets, a cold store, and three unisex boutiques.
I’m a lawyer and don’t always have time to oversee everything, so I trusted him to handle it. Things were going well at first, and the employees were doing great. I didn’t want to interfere much because he seemed serious about managing the businesses.
But now, with his demand for a second wife, I’m heartbroken. I told him that if he wants a second wife, we will have to get divorced first.
He agreed. When I said I would take back everything I’ve given him, he responded, asking me if I thought he would be poor without my businesses. He seems to have forgotten that I’m a lawyer, and I have the knowledge and resources to make him regret this.
I love him, but it feels like he has used my money and resources to build his life, and now he wants to throw me away. I could ruin him, take back everything I’ve given him, including the businesses, his money, and even his personal belongings, but I don’t want to go down that path unless I absolutely have to.
Since the argument started, I’ve been recording our conversations, trying to gather evidence. I provoke him into saying things that I could use in court, though I don’t want to harm him if there’s still a chance to fix things. Relationships have always been difficult for me, and many men have let me down, but I truly loved him with all my heart. I introduced him to a better life and gave him the confidence he needed to succeed.
Now, I feel like he’s taking me for granted, and I’m not sure how to handle this. I want to know if there’s any way I can change his mind before I take any legal action.
Can you offer some advice on what I should do next?
