Take the class, it sounds like a great opportunity to work on yourself. From my experience that is what DBing is all about, making yourself better.
As for the question about rubbing the A in your face. I think in their weird twisted kind of way they feel they are being considerate. They are going to do it anyways and by asking you they think that they are taking your feelings and concerns into account. Messed up I know, but this is how they think.
My W at one time told our pastor that the A was over and our mess was do to everything else in our M. Well two days after she talked to our pastor I found love letters and proved that the A was still ongoing... Why did I tell you this....Well about a month after that she told me that is was able to say that the A was over because it was only talking and that they hadn't had any MOMENTS for a while. MOMENT = make out session...... She was able to justify the lie in her mind so it made it OK.
Remember that she is wrapped up in this dude and as crazy as everything they do seems to us it is justified in their heads.
