I don't know about this, not in that I don't think it is a good idea but I really don't know about this. So I thought I would offer a diffrent perspective and have everyone tell me to shut up.
So W brings BF around you. Why? Women think diffrently, at least that is what the books tell me, so her reasoning is probably to inflict pain on you since she is upset and looking to justify why she is upset, see GD another guy will pay attention.
What will she think in her head if she does see you with these women? Could it be similar to what she thinks showing off her crappy BF? Maybe some of the women on here could give there view, and does that move you closer or further from the goal. Just don't want to send the wrong message, maybe thats not very DB, cause it sure says done if you have some eye candy buying candy.
Now all of that is mute if we are talking slurpee's, well then of course everyone knows that those things rule and you have to stop. Wouldn't matter who your with or what is happening because the wonderful flavor of it all trumps feelings.
