Leading a person...out the window of the second floor

I only know one entity that actually does that, and it's called The Winchester House in California.  It's this nonsensical house that has stairs leading people up straight into the ceiling, and doors that lead right outside of the house on the second floor.  It scares people, and probably instills regret to some visitors of the house.

So what do the bizarre features of this house have anything to do with dating?  Plenty, considering that doors that could cause you to fall one story are just as painful and infuriating as being led on.  It's unnecessary pain and grief.  

That being said, how do you know if you're leading somebody on?

If you are a guy, chances are it would be blatantly obvious because guys are expected to initiate most things.  He's the one expected to do the chasing, the asking out, initiating the physical contact, etc.  It's a more proactive role to take on.  He could choose not to call and that's already the message in and of itself.  When a guy is leading somebody on, he continues to actively do the things that build attachment.  This is a lot different for women, however.

When women are accused of leading a guy on, it's because just dropping him doesn't cut it.  
When she goes along with it, it tends to be more passive, as opposed to actively asking out.  
It doesn't take much to be chased, so allowing a chase to continue can be so much as not lifting a finger.
Problematic much?

Overall, guilt is a good indicator of leading someone on.  If nothing's working, then a different approach must be taken in indicating disinterest.  The tables turn and the roles reverse when there's disinterest: men become passive and stop taking the lead, and women have to be more active and state their disinterest.  It's not always successful because a man's disinterest tempts a woman to goad him along and makes him even more unsure of his feelings toward her.  And we all know what happens when a guy does not take no for an answer.

Sometimes it's inadvertent.  It's still hurtful all around when at least one party doesn't know what they want and just continue to date the same person aimlessly.  It's morally less heinous than dating for supremely selfish reasons and throwing respect out the window, but it's still hurtful.  So it'd be good to know how to prevent that too.  Be sure of your feelings.  Your future partner will appreciate it greatly when you can identify and articulate your feelings to them, so it's a good habit to have.  Can't do it yourself?  That's why you have a support network.  As annoying as it can be to be teased by my girlfriends about how the date went, I realize that in telling them, I'm also letting myself know if I'm really starting to like the guy.

Or if it's time to cut my losses and to warn him to watch his step.
