All love shifts and changes. I don't know if you can be wholeheartedly in love all the time.
The Fault of It
by Ezra Pound
Some may have blamed us that we cease to speak
Of things we spoke of in our verses early,
Saying: a lovely voice is such as such;
Saying: that lady's eyes were sad last week,
Wherein the world's whole joy is born and dies;
Saying: she hath this way or that, this much
Of grace, this way or that, this much
Of grace, this little misericorde;
Ask us no further word;
If we were proud, then proud to be so wise
Ask us no more of all the things ye heard;
We may not speak of them, they touch us nearly.
