Having a crush can be a beautiful thing - if they like you back. But if the object of your affection doesn't return the love, you can be left with crushing disappointment, a blow to your ego, and possible heartbreak. Rejection is a difficult, albeit inevitable pill to swallow in life, but especially when it comes to dating. The trick is to know when you've been served that pill and how to walk away gracefully. Otherwise, you look like a desperate creep. A Reddit thread has asked guys for the moments that made them realize, "this girl is definitely not into me," and the responses are painful to read. I'm not sure whether all these girls are nasty individuals, or the guys didn't get previous hints to back off, resulting in drastic rejection measures. What do you think?
