What would you do if you were in mom's place?

This story is inspired from a drama.
In a hypothetical scenario, we have a family of 4 people, mom, dad, their 10 year old daughter and mom’s aunt.

The mom’s aunt has a health condition where she has to live with her niece and her family.

Suddenly the mom finds her husband cheating and has impregnated his other partner. Now she’s in the process of divorce…

She’s also aware that her daughter is a genius with an IQ of over 180 and with her school she receives an offer from foreign country to receive scholarship for further studies in some great school for geniuses… It was a great offer.

But travelling and visa costs a lot, with over $50000 and the family was already in dire financial situation. The mom takes help from her now, ex- husband for help. He apologizes for his mistakes and helps the mom with half of the money, mom takes the rest of the money by taking a loan with her business as collateral.

Everything is good to go, but the daughter is quite attached to the mom’s aunt and don’t want to leave her due to aunt’s condition. She wants to stay in her own country and continue her studies in normal school.

The mom also don’t want to let her go, but she knows it’s for her daughter’s own good. The daughter’s gonna stay in foreign country for few years if mom sends her.

So what would you do in you were in mom’s place?
Sorry for the long question, i had to put down all the variables.

I appreciate the answer.
Regards!
