I am possibly neurodiverse, and this isn't something people are direct about.
If you arrange twice to meet up with someone (specific date and time) and they cancel twice last minute, is it safe to assume they aren't interested?
If you message someone asking to meet up and they say they are busy for the next month and don't suggest another time, what should be interpreted from that?
I assume it's an indirect way of saying 'I'm not interested'. But since it's indirect it's difficult to know. Any general rules?
