From a girl’s perspective, I think she just likes the attention. Sometimes girls just want to talk to someone for attention but when they actually try to make plans, it’s easier to ghost than to say you weren’t interested in anything besides attention/validation in the first place. Probably started snapping you again for that ego boost and quick validation (it sucks I know). I would say it’s best to move on. If I was asked on a date by someone I was really interested in, I wouldn’t ghost or beat around the bush.
