Personally, I can't help but to look down on guys that pull junk like this. I know a few people that are like this and kinda laugh at them from time to time because they'll turn to me and my friends to try and help them get with the person. If a guy keeps on pushing and won't take no for an answer, sometimes you've gotta throw being polite out the window and just tell them blatantly as possible "it's not gonna happen" and maybe cut all ties and connections with them. Of course people that pull this crap are probably stalker material some time down the road too, so sometimes a restraining order might be involved.

Suck it up and move on with your life, I knew people who would get really depressed because they got turned down by people and then they turn into this reclusive creature that all they can do is start complaining about crap. Call me a soulless abomination, but I tend to laugh at them when they start turning into some sort of "attention seeker". I've been turned down and, like other things, I tend to be unfazed by it and just don't dwell on it and make it worse than it really is.
