Bandmate went off on me when I asked about money I was owed from gigs

Title.

I play in a classic rock cover band. We played 2 gigs last month and I have not yet been paid.

I sent a message a week ago to our frontman (handles the money) and he said he had to get the check from the one venue (he got too drunk at the gig and forget to get it). A week went by and no money still so I followed up in our group chat.

He went on how his mom is sick and he has been helping her out etc. While I feel bad, he also could have asked one of us to help? He proceeded to go off on me how it’s always me with the issues. This guy also brags about how he makes “lots of money” all the time.

Am I in the wrong? While I feel bad about his mom, I feel like he is just using it as a bigger excuse. He could have asked one of us to help take care of it. It’s going on 2 months now since some of these gigs.

TIA
