I would end this virtual relationship. Number 1, it's not a real relationship unless you have met in person, know what each other is like in person and spend time with the person for real. People can be anyone they want to be online and often lie. So it's not real until it's actually real. Number 2, she has a boyfriend and has emotionally cheated on that boyfriend. Is that the kind of character in a woman that you truly want? She will likely cheat on you, too. That's how it works. And she has proven that already by flirting on this secret account. In my opinion, she is playing with fire being online as she is and flirting with people on these different accounts. I feel badly for her boyfriend.

So, I would end it and find a real girlfriend that you can get to know for real and in person. This relationship will never lift off the ground.
