For a bit of background: I lent $2k to my ex when we were together and we both agreed that they'll pay me back. Broke up with them 4 months ago and recently messaged them to ask to return the money. They said that they won't as it was a gift. I have screenshots proving that it wasn't. I have told them that if they won't return I will talk to lawyers. I messaged ex's sister to ask the sister to speak to my ex and hopefully help them see that they are in the wrong. Sister offered to pay for my ex instead, I said no. I feel like it's my ex that needs to own up to them selves. That's not how you treat people. Since talking to the sister of the ex, I get a message from the ex saying that his dad has been very upset about it and is experiencing auditory hallucinations bc of me. Bc I am demanding my ex to pay me back. The money was lent to them 5 months before the breakup. It's been now total of 8 months since I lent the money and not a cent has been returned.
I feel bad for the dad but I feel like if the ex has saved up little by little, then this wouldn't be happening. AITA?
TLDR: ex owes money, refusing to pay back. Ex's dad is having auditory hallucinations bc of stress knowing that their child (ex) owes me $. I am thinking about going to see a lawyer and start a small claims lodgement.
