Romance scam but not asking for money?

Has anyone experienced a situation where you've been chatting online to an account for months, and their tragic stories seem almost too messed up to be true. The lovebombing started very early, and this person seemed infatuated with having my attention. There had been lots of gaslighting, emotional manipulation and other red flags for me. But, one thing that confuses me is that they never once asked for money (they did one day offer to buy me something that I was wanting to buy though, to which I didn't respond to anyway). One day, they randomly told me out the blue that they feel they don't know a lot about me but they feel I know a lot about them. It felt like at many times there were attempts to get private information out of me but in a very subtle, non obvious way.

Anyway, I wanted to see if there's others out there who had a very off feeling about who they were actually talking to for various reasons, and if there's others who also weren't asked for money but perhaps had given away some personal details? Are there long term con artists who purely go for personal details?
