There is a subtle rhyme scheme within this write which makes the poem smooth to read and at the same time felt. I had to re-read it again the second stanza as it did not flow but it did.

For inside the meaning of love,
is loyalty and trust,
and to do what is best for you,
not for me,
is a must!

^^Its a dreaded moment for all of us who have to face the "letting go" phase. at first we are too stubborn to allow it and yes it is out of selfishness but when you see someone-pet or human suffer the brave thing to do is let go. Its easier said then done. Nicely penned.
