If she says that she wants to see where this goes with him...he must be more of a factor than she says...I really agree with her to some respect...I don't think he has long term potential, security, stable, etc.
I know it's an ultimatum and it disagrees with DBering, but T endorses it and W kinda listens to T I think. I mean isn't there something to say for "Ok, I will hold off on D and work on myself and the M but I would like you to do the same...even if it is just for 4 weeks?"
If she chooses OM, I would just want her to be happy and that is the most unconditional love I can give.
