I would say if the A is continuing - hold your course. Minimal, pleasant, guy with other places to go - not going to hang around for some woman who isn't going to put him first.
She's temp checking I think. She may not want you right now - but sure as heck doesn't want someone else to get you. Have you read Sandy's thread on WWs?
Beware of getting into the 'friend' zone or gratefully hoovering up crumbs. Until or unless she chooses to end this A and recommit to the M, you are moving forward as if she is never coming back...
JMHO of course, but I think strength and resolve and losing the fear (of losing her) are the way to go...
