Personally I’m astounded that a person of apparently reasonable intelligence can’t figure out what to do in this situation.
Just write down your choices on a piece of paper and, yes, that one good choice among all the terrible choices is the one you should choose. I don’t want to insult your intelligence by telling you what you should do in this situation.
Here’s a hint. If you allow this person to be in a position to rip you off for a single penny more you’re 100% at fault.
Everyone’s life goes through good and bad cycles. It’s kind of like investing. Make the ups as big as possible and make the downs a minimum. If things are going great there will be a downturn at some point where more challenges hit. Don’t worry about when it will happen, just make the most of it while things are going your way.
When things seem to be falling into place it usually means you’re making the right decisions.
