Some advice

[Matt]

Need some help. Basically the ex has paid me any money for the loan I took out for her for a new car.


I took the loan out to buy it, we then broke up, I continued to get payments from her up until sept but I haven't recieved anything since


She isn't responding to messages etc and I had to text her mum to ask about it and her mum said she has paid it all.
So what do I do? There is about £800 left on the loan, I have a bad feeling she isn't going to pay, and I'm not in a financial position to take it on.


So, her name is on the log book etc
But I paid for it.

What are the legal grounds? Serious answers please
No "go fist her" as I need this sorted
