What would you do or abstain from doing?

A question pierces through my mind, bringing back memories of when we were both lovers with unshared love. It makes me forget my past promise to leave it all behind, to search love in new horizons. Makes me feel the hope to get back in your arms not just for a passionate night, but for the rest of a life who'd break up with all my beliefs, all my expectations. Which I'd sacrifice for a life with you. If you had a second chance, you ask, what'd you do? or better said, What would you not do?
