AS long as this is not causing you pain and you feel this gives you insight into her, then stay the course. The thing about DBing is you do what works and throw out what doesn't work. Detachment is the name of the game and if you can remain detached then go for it.
I think this is something people forget on here. There is no "one size fits all" approach to DBing. What works for me, what works for SS, probably won't work for someone else. The guidelines are here for a reason, they work, but it's up to each individual to take those guidelines and apply them to how it fits into their own sitch.
I don't see anything wrong with approaching the EA/OM, like SS said, as long as it doesn't affect you in a negative way. What's your 'ultimate goal'. As coach always says, does what I'm about to say, or what I'm about to do, take me closer to my goals, or take me further away? Only you can know the answer to that.
