Those are the only two things I've seen work. If #1 turns up nothing, then proceed to #2b. And in the meantime, GAL your ass off, and become the better option. Best case, you'll attract them back, and at a minimum you'll become a better person that will be more attractive to SOMEBODY in your next relationship.
Thanks, but you still missed my best one, yesterday. I even put a "Yes, Ready2Change, you need to STICKY THAT SUCKA!!" in it.
