Hello Mamuka!
Three is incorrect. Instead, you would say "Thank you for being you."
Thank you for breaking my heart is not suitable for Valentine's day. This means someone broke your heart, i.e. broke up with you.
Some other examples:
Thank you for being my all.
Thank you for being my everything.
Commonplace and popular are a bit like "chicken and egg problem". It would be unlikely that you have one without the other, if only state specific jargon. To this end, I would ask you: Does a phrase have to be popular to become commonplace or does a phrase have to be commonplace to become popular?
