Could be, yeah. I'm a bit skeptical though. This took place months ago, and the conversation ended in a pretty reasonable place, something like "nice to meet you, take care" from me. I would have expected a few more engagement attempts from her if she wanted to scam me.
Well that's part of the romance scam game, you don't want to seem too needy. The best romance scammers will play a little bit of "hard to get" and a little bit of "good cop bad cop" if you know what I mean. The aloofness that you describe here was not an accident.
