My ex gave me 14K in the time we were together to pay off some debts. Now we've broken up, he's threatening to sue me if I don't give the money back. I never signed anything and at the time took it because I thought we had a future together and eventually would share the same bank account anyway. The whole time we were together, I cooked, cleaned, washed, and looked after his property and animals while he was away working during the week. I didn't sign anything to say I would repay the debt. He knows I cannot pay him back the whole lump sum. Do I legally have to give it back to him? It felt very uncomfortable at the time taking it but he nagged me until I caved.
