Lost outlay

You left
Your foot print
On the pebbles
Where the tide breaks
For me to step
& follow your way
On the mark you lay
The first was dark gray
Second I though I may
For the third I pray
Then lost in hey
The tides say
I'm not in right way
Disconnected to convey
She moved away
Out of my outlay
I can't replay
But blame the day
The tides & the purple ray
& my fortune that lay....
