"This troper" examples for yandere. Just seeing the title made me start shouting "no".(I think the fact that I have a certain amount of stalkerish tendencies that I've had to learn were a problem might make it more bad for me, but who knows.)
EDIT: but not "yandere" tendencies. I probably shouldn't have said as much as I have... It takes too much context to explain.
The "This Troper" section has since been wiped from the site (these videos pretty much show the reason why) but all the turbo-nerds who wrote them remain.
