I caught my husband's secret account and the balance nearly finished me

I have been married for 6 years. We have one daughter. Everything seemed normal until I went to register her for school and the fees were more than we planned. My husband said he would sort it out. That evening he went to the bank and came back saying he had transferred the money.

But I saw his phone later that night. The bank alert was still on the screen. The account name was his, but the balance made me freeze. N4.8 million. Our joint account has never seen that kind of money. We are both civil servants. How? I did not confront him that night. I just sat there thinking about all the times we borrowed from my mother for school fees, all the times I said no to buying new clothes, all the times I told myself we were managing.

I have not asked him yet. I am scared of what the answer will do to us. But I keep looking at our daughter and wondering if the man I married is even real.
