Hos, do your best to emotionally and intellectually escape from this, right now. Just make sure it's legal, moral, and ethical...
There are those on this board who will remind you that there are plenty of instances where D was a necessary step to R and back to M. It DOES happen. D is not necessarily the end.
That said, the M ain't over... 'til it's over. She might be fast tracking and it might appear that she has a fan base for D, but that does not mean she can't just as abruptly stop in her tracks. Something could trigger her to doubt her direction as strongly as whatever it was that triggered to move full steam ahead right now.
Patience, my friend. Focus on your hobby... and make GALing your hobby...
