AITA? Flatmate Drama - My Drunk Flatmate’s mistake cost me rs. 10,000

I live in Bangalore with 2 other flatmates in a popular society in Bellandur. This one night my flatmate started doing some Nashe because his Hinge date stood him up at the restaurant.

I was like whatever. Who even cares about this. I had to go on a date with this girl I had been seeing for a couple of weeks.

We went to Ironhill Bangalore and had a great time. She said that she wanted to see my society. So we went there afterwards and one thing led to another and we ended up in my room.

The next morning when I woke up I heard someone scream. It was my flatmate who saw my date leaving and he started crying saying that she was the one who stood him up. I took him to his room to calm down. Tab tak she left.

Later that day he started drinking a lot because of this and blamed his qismat. I did not know that he was drinking and I only came to know later. That was a big mistake for me.

I had to go on a trip the next day so I was busy packing. I asked him to get me 10,000 cash from ATM while I would go to get printouts of papers I needed in my village.

He took my wallet and left.

2 hours later. He came back home and gave me the transaction receipt. Apparently, he kept the transaction receipt in his left pocket and ripped up Rs. 10,000 ke notes in full Nashe and threw them away thinking that it was the reciept.

I slapped him so hard that day and asked him to vacate the flat. Made him sleep on the bloody footpath that night.

AITA? What else could have I done?
