That's not a very good indicator/sign for PL women isn't it? I'm sure the OP would like to know more about singles more than the divorced or separated.
I think it's a very good sign. After all, unless he's looking for someone very young or for an old spinster all probability suggests that the person he meets will have had previous relationships.
And don't forget the OP is separated himself.
And it must be really that bad that women are divorced or separated. It reflects poorly on the kind of women in PL.
It reflects very well on them, unless you think there's something admirable about hating yourself so much that you stay forever in a dead relationship.
