This is a really good question. Been thinking about it lately too. My theory is that you don't know if you are going to click with a person until you step out and take a chance getting to know them. BOTH should realize in doing so you are taking a risk with your heart. But also both should allow a person to graciously bow out from it if you see that it's not working for you.

Dating someone is not a commitment to marriage. You gain much knowledge about yourself from dating I suppose. WE should be a little easier on the guys who decide we aren't ringing the bell for them. And visa versa......In doing so you are taking responsibility for your actions.
