edit: During the end of the night, I mistakenly texted him that his bet was winning. He kept asking me if I was sure so I got suspicious and looked through my texts, I realize it was not the bet he picked and that I have confirmed for. As a result, I told him that his bet lost but did not mention about the wrong bet I made.
Does it matter if the wrong bet won or lost to him? Fortunately for me, the wrong bet ended up winning. I'm thinking if the wrong bet were to lose, I would assume the risk and therefore he should pay for the bet he lost.
My question is..
Should I ask for the money if his bet lost? Or give him money if his team won?
Should I give him the money if the wrong bet I made won? Or ask for the money if the wrong bet lost?
Who is right or wrong here? What should I have done?
