Rules of Quitting...

Question…if you are early on in dating a person and for whatever reason you decide to quit them, do you need to officially let them know they’ve been quit or is it ok to just disappear? Now understand with this I’m not talking about a serious relationship b/c clearly that deserves an actual ending. But let’s say you’ve only gone out on two or three dates and you realize they just aren’t it. Can you just slowly stop returning their calls or stop accepting dates and try to end them into the friend zone? Is that rude? What if you’ve given them some lovin and then you realize it’s just not going to work…does the introduction of lovin warrant a face to face quitting? What’s appropriate?
