Ummm yes, she was dishonest with you from the beginning...she is doing exactly what she wants to do in the way that SHE wants to do it...is it what YOU want? It doesn't sound like it...sounds like you got fleeced by a jerk.
I am sorry though, you deserve, we all deserve better...I wish more people would make an effort to get to know people away from the devices, it would save heart-ache.
If it was in REAL time you would have found out a lot sooner than 3 weeks, right? But the internet/texting thing makes it easy for liars to lie.
It takes a while before you can trust someone with your precious heart...make em show with their own actions and words how valuable that is before you set your heart out there for the predators to chew up!
