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?

One is also incorrect - I didn't write this as someone had already written it for you. The correct version of one would be to say "Thank you for being in my life". Also for your question you would ask "What else is incorrect?" rather than your phrasing. Native speakers do not use "which else" phrasing. You could say "which is incorrect?" but which is not used in combination with else. Hope this helps!

Definitely not 3! 1 is incorrect, the others are ok. It's difficult for a phrase to be popular without being commonplace.
