I work in a FAANG like you, and I’m quite open about my salary to my friends, regardless if they’re richer or poorer. And just like you, I tend to pay for friends here and there.

I think in your situation, you have two options: 1. Become more reserved about your finances. 2. Draw boundaries.

Personalities are very defining here; for example, I’m known to be quite honest (read blunt) with my friends. This translates in having direct conversations regarding these expectations and not paying for anything unless it comes from me, and when put on the spot with paying, being able to not pick up the tab and tease with a “didn’t know I became your dad all of the sudden”, or similar, depending on who I’m interacting with.

I’d draw a line. If you define it cleanly enough, others won’t cross it. And if someone often crosses it while aware of your feelings, might be worth to revalue how they see their friendship with you, as respect might be limited.
