how long until enough?

How many times can someone put their heart out there.
How long can someone hang on.
When is enough enough.
How can someone keep enduring it.
Is there any way of getting through.
How much does it take for a heart to explode.
How many times can someone be hurt.
When will it get through their head.
When is enough enough?!

No one said it would be easy, they just said it would be worth it..................?
Umm...I guess I'll have to see it to believe it because it doesn't seem that way at the moment.

I must be a masochist.
