as a general rule i’d say its a no-no
i’ve been on the receiving end of this from a woman who just let it drop in conversation
granted it was a first date but felt like i was being played as the initial indication was she was divorced
leaves the feeling she is looking around to trade up but not ready to kick the somehow unacceptable hubby completely to the curb
also you leave yourself in a position of having your heart handed back to you in pieces later when they decide to get back together since you really have no basis to complain you knew the situation going in
suffice it to say i didn’t call her back
