I just happen to look at these relationships that come during the divorce from the shoes of the other person. A lot of people say "I'm just having fun, or seeing that happens, or "it's ok if I'm happy, even just for a little while"
I have been on the receiving end of more than one of those relationships. Words would tell me one thing, actions would tell me another, and I never knew where I stood. None ended good and I got hurt.
