He said his only relationship with her was online? Well then, he is living in a fantasy that never had the fruition to become a reality.
Yes, fantasy can be much Lovelier than reality! However... He needs to wake the fuck up.
Unfortunately he needs to drink a hard dose of reality.
Yes, I get it that you like/love him and all even though you don't really admit it with what you're saying... in my opinion, the best thing that you can do is to leave him to his own devices... Alone.
At the point when he starts Crawling Back to You wondering why you are ignoring him... You could explain that hey, I'm tired of waiting for you to come around comma if you have an interest in me you need to let me know because otherwise I'm just wasting my time. In other words... What I'm getting at is that's exactly what's happening between you and him... You are wasting your time. If he can't see what he has with you then he is not worth keeping in your life as a love interest... But if you do not leave him to his own devices, he will continue to take you for granted and will not have the opportunity to miss you or think about you or have a longing for you that you are seeking from him to find out what his true feelings are for you... My point is, is that he is probably not aware of it himself and you need to give him the time to figure that out and nothing does that quite better than the fear of losing someone and being alone to think about it.

All you can do is move on from him. He is obviously in love with an illusion, because he has never met her in RL. When people meet on-line they build an imagine of what their lives could be like together, and what the person is like in reality. In most cases when two people do meet up their illusion becomes shattered, because the person is not what they imagined them to be. So he is obsessed with a girl he thinks he knows, but in reality their life together would not be what he imagined it to be.
You did the right thing by ending it. I would never give a guy my heart when his belonged to someone else's.
