Line with X's towards the outer edge: The X's represent personal betrayals against you.

The Life Line
Your life line is the curved line that is stretched around the thumb, While you might think that it would reveal how long you would live, it's actually a little more complicated then that.

Short line: If it ends in the center of your palm it means you like to keep busy when you are dealing with emotional situations.
Faint line: If it is particularly hard to see then you are a low energy person who doesn't seek out adventure.
Broken line: Every break in the line indicates a traumatic experience in your life that has managed to impact your decisions.
