Even if there is no chemistry it doesn't mean you have to dehumanize them, catfish or not (and a few lbs more than pics is hardly cat fishing). Have a lovely dinner, chat and find some mutually enjoyable topics, have a fun time out. And yes, tell them the next day that you enjoyed yourself but are not interested in continuing further. It is that simple, and super easy, and everyone walks away feeling good. (because let's face it, you probably aren't gods gift to women and she will recover just fine)
