How Do I Get My Wife To Pay Back Money I Loaned To Her?

It started like this,I give her money to start business after much pressure from my mum that you need wife to be doing something bra bra bra. I gave her 100k to start. She later returned to tell me that the money is not enough since she needed to secure portion (OK bizz). I gave her another 100k that is not my money(meeting money)because I am the treasurer but i didn’t tell her that it is meeting money and meeting is closing next month.

When I ask her, she said that husband doesn’t borrow wife money and get it back I should ask my mum. Elder please is it true b/c I don’t know how to make 100k in the next 3weeks.
