"There has been no other,
That I have known before
Where from the start,
I just completely adore"
- I think in the last the flow would be exceptionally better (not that it's off now) if you remove 'just' in order to have 'I completely adore'. I liked these lines, they put hope, faith, and stubbornness into the poem.
"So caring, humble and kind"
- This is a very overdone mistake, easy to make too. 'So caring, humble, and kind' is how you want it (note the comma after humble). Many people forget to add one not realizing it's needed or simply think that it's not. BUT, you need comma's in lists. Examples of non-listed, non-needs; Bruised, black and blue.
Note: Black and blue is a saying/phrase but it's a list with bruised. Therefore you don't need a comma after black since it's tied in with blue.
"Will such a day ever come
I'm just waiting here, just waiting here
Waiting for that day, you say you'll always be there."
- Three lines? I suggest separating the last line at 'day, you' to make 2 lines like;
[Will such a day ever come
I'm just waiting here, just waiting here
Waiting for that day,
you say you'll always be there.]
I'm going to let you in on a secret, kiddo. There's ALWAYS another guy/girl out there for someone. But, the person needs to take into consideration if that person will meet the standards they have set and/or if that person will be better than the last. Keeping secrets isn't fun to do. (That's my secret, lol).
Of course, keeping secrets fits your name? Mysterious. Haha.
