Well, just so you know, there are some veterans on this forum who are very, very hardcore about how you treat WAW when they have an OM. Go over and check out 'A in Ohio''s thread and see the posts from Puppy, Pheonixduex and Little Engine.
But I am a bit more moderate. If she reached out to you and you're interactions are positive, then perhaps it is OK as a starting point. But at some point you are going to need to make it clear to her that it is you or the OM, not both.
If you wait too long to confront her on this topic, you are just setting yourself up for hurt. When you force her to chose, she may very well choose OM. And then you will have gotten your hopes up while she was just enjoying the chance to have you both.
Good luck my friend.
