Long-term FWB is not going to work for you, or this thread wouldn't even exist. You'd be rolling with the punches, enjoying the sex when it happens, and not expecting it become more than it is. You would recognize that this is how FWB goes - not speaking all the time, not officially dating, not having sex with strings attached.
This is all going to prove a waste of your time. She also didn't take advantage of you if you were a willing participant and clearly knew you were not her boyfriend. You would be best to let her go and stop having sex with her, too.
