I think you are in general very trusting. It’s good to be trusting but to a point. Whenever you meet new people you want only to see good in them. And it’s not wrong, it’s just who you are. Sometimes it might be wiser becoming more careful in who you trust and take your time with people. I don’t even think they are bad people. Just not people you can trust to be on time or make commitments. People are who they are. At 59 for sure they aren’t changing

Honestly I have family members like this. It’s infuriating but we kind of stuck with them. Good for you cutting ties with these folks. Don’t even have to be rude. Say hello. Just don’t make plans.
