So there's this new guy at work who I'm pretty sure is (or rather was) being flirty. He was doing the whole singling me out and making prolonged eye contact thing, but at the time I'd brush it off, mostly because of shyness, but also just because getting involved with a coworker probably isn't a good idea. Either way, he's stopped doing it now, so presumably he thought I wasn't interested in him. The only problem is that I am. He's really hot lol. So the question is... can I get him to start doing that again? Or do guys irreversibly lose interest when a girl appears to reject the advance? Like the rejection kills the tension, so to speak?
