Four years ago I (38f) borrowed $8,000 from my mom (60f) for a down payment on a house to be close to her. Three weeks after I borrowed it I had earned a commission to pay her back. However, she wanted to give my bank info to some guy at a store to transfer it obviously I said no. I offered a check or to help her at the bank she said no thanks and wouldn't take the check.

I took an opportunity to go to another country and I broke even on selling the house. On top of as soon as I arrived in my new country I suffered a severe burn that required surgery and time off work so I'm a bit strapped. She wants to buy a condo in Mexico and doesn't want to sell her stocks, second house that my brother lives in for free. She wants me to pay her back but I feel like she waited till I didn't have it and she has so much already that having a third home feels like not my problem. We've always had a terrible relationship and I don't know if I'm being jaded. Am I wrong to not want to pay her back now? I offered to pay monthly but I don't know how to do it when she tech challenged.
