If it’s only been a few weeks, then I think you had a right to be cautious. Like Bill3, I personally wouldn’t like to do a video chat so soon into meeting a stranger online either, but I would try and be understanding and reassuring rather than put the blame on them for being insecure/untrusting. You didn’t feel right about it, maybe you do have regrets but it doesn’t mean you made the wrong choice.
I’ve had strong attractions like this, too. They all passed in time, but it was hard to let go. You just have to keep working on distracting yourself, and maybe examine what led you here.
It’s something I might even bring up with my own therapist, although I gave up connecting with potential romantic partners online several years ago.
