I have been on MN for years but have name changed for this - and the name says it all. I am terrible with numbers (it actually has a name, dyscalculia).
I have also changed all the identifying detail because nobody except me and "Tom" knows about this transaction so I can't ask anyone IRL.
John has a car for sale at £100 and is desperate to get rid of it
Tom would like the car but has no money. He would be doing John a favour to buy it
I am John's partner and I lent Tom the money to buy the car, John doesn't know this
Tom paid John and took the car
Tom has signed a contract to repay the £100 to me when he can. I thought he was mathematically literate but now I have doubts.
Does he really owe me anything? Do I owe John/does John owe me?
By the way, if John owes me I'm not going to say anything to him, but of course I will tell Tom and tear up the contract.
I feel terrible now (and stupid), please help (it's more than £100).
