I want to warn people that I have ghosting/flaking issues
Can you tell specific people and not everyone?
I am not sure about that.
It is good to be open and honest with people. You should try to be nice about it and not drive people away from you.
Nah, I think it is enough to say the warning. People that might care would ask me about it and those that wont won't.
I'm glad you can see your flaws and are willing to address them. Have you ever talked with a therapist to discuss why you ghost people so much?
