>Third, as many have pointed out, it was entirely my fault for the fuckup.


No, it was not.

First, doubting the identity and intentions of online strangers is perfectly normal and is in fact what any reasonable and smart person should do. No one will argue if you assert that you cannot trust a virtual acquaintance, let alone a newly made one.

Second, if that girl in question fails to understand the aforementioned rather obvious truth and take it as a given (which it has been for quite a while ever since Internet became a thing), then you're better off the way you are right now, losing contact with her.

Be well.
