Does anyone knows what they really want in life?
Well i don't think so, that's why people take risk exploring and experiencing new things.
There's really nothing to lose, but if you didn't take the risk,
You'll probably have this thinking of "what if" and regret that you didn't take the chance.

But once you know that something is bad for you, of course it's time for you to let it go.
Just like love, you let go. If it does come back, and dont leave you again and again, it's yours.
If not it's just another phsycoligal method to get people on their "hook".
"Hook" meaning giving the person a light of hope for you to be together but just for him.
In reality, this kind of person would do anything for that other person because he/she thought he/she might have the chance to be together but it's not gonna happen ever.
Mostly they would use the word "i can't be with you right now" or "i don't know what i want for now".
Sadly i've experience being hooked by one.
After looking back, i feel very stupid and really looked like a fool back then.
That's why if you notice you're being used or the other person only look for you for benefits,
the answer is "Leave and Move On Immediately".
This kind of people only find you when they need you, but when they don't, basically you don't exist, you're only exist when she needs something from you.

So please be careful and don't get yourself "hooked".
