Good day! I'm trying to write a quote..<br/><br/>"I <b>have wanted</b> you to be mine, from the very start.<br/><br/>It's just that, I still haven't figured out <b>(yet)</b> how did my last one (relationship)<b> have fallen</b> apart."<br/><br/>Do my usage of have in the quote above correct?<br/><br/>Can I insert the word "yet" there? Or is it more natural not to put it since there is already the word "still"?<br/><br/>And I would appreciate it so much if you will suggest some improvements to it to make it sound more natural and poetic.<br/><br/>Thank you in advance!
