AIO How should I feel about my childhood friend after this?

So, I (20M) have two really close friends—S (my childhood friend) and N. We’ve been through a lot together, and I genuinely care about them.

The situation that’s making me feel some type of way happened a few days ago. Some friends from another city came to visit, so naturally, we all went out to eat. Now, money has been tight for all of us, and both S and N were broke at the time. Since me and my other friends had some cash, we decided to split the bill and cover for them. No big deal.

Here’s where it gets weird. Later that night, we found out S actually had money—not just a little, but literally three times the amount of the bill. My first reaction wasn’t anger. I figured maybe he had a reason for not spending it. Maybe he needed it for something important. Turns out, his reason was that he wanted to buy new clothes. Now, don’t get me wrong—I get it. Wanting new clothes isn’t a bad reason, and it’s his money at the end of the day. I let it slide.

Fast forward a couple of days later, S, N, and I were hanging out again. I was on my phone while they were talking about life, and S started going on about how N doesn’t understand people and how low life can get. He was saying all this deep-sounding stuff, but honestly, it wasn’t that deep. For context, he recently went through a breakup, and it hit him hard—like, “I can’t live without her” hard. N and I were there for him, helping him get through it.

Now, here’s the part that pissed me off. While talking about how he always plans ahead and thinks about the future, he brought up that night we all went out to eat. He literally said that not disclosing his money was part of him “planning ahead.” And I’m just sitting there thinking, Dude, what the actual fuck?

We were literally counting every penny while ordering so we wouldn’t go over budget, and you—who had more than enough money—just sat there and let us cover for you. And now you’re acting like you’re some mastermind for it? And on top of that, lecturing us about planning ahead?

I didn’t call him out on it in the moment, but man, this just left a bad taste in my mouth. It’s not even about the money—it’s about the mindset. I’ve known him since childhood, and I don’t know if I should just let this go or if it says something deeper about him.

What do you guys think? Am I overthinking this, or is he just selfish?
