Ahhh they just don't make 'em like that anymore. The love and pain that poured forth form this era of Yeats has always tugged at my heart. Even the title of your third choice, Never give all the Heart is so telling and so very sad, but like you said, it makes you wonder what his poetry would have been like without his unrequited love.
Thank you for bringing a bit of the classics to steemit. I for one appreciate it very much!
