This isn't the place to ask but I need some opinions?

This happened all in one day today.

My boyfriend and I went to atm to take cash out for rent. I handed it to him to give to his brother to collect when we got back home.

An hour later, we went out to get a couple of snacks. He had $30 in his wallet when we left. He spent $16.

We got back home and he gave his brother a $20. I didn't know but I asked his brother to confirm. Which doesn't make any sense because he doesn't have enough to give.

My boyfriend is drunk as hell right now and I didn't see him buy any alcohol/shots. His wallet also contains more money than when we left the house

How is this so?
