Leaving is the hardest thing I ever had to do

Leaving is the hardest thing I ever had to do,
but what hurt the most to me was having to say goodbye to you.
Will be still the same the next time that we meet,
or drift apart and change like two strangers on the street.
Time can only tell us what will lie ahead,
but will time fill my vacant heart just like when we met.
The tears finally fade and my feelings disappear.
If anything at all, this I have always feared.
Now that I've left you, will I ever learn,
Always knowing deep inside, that I can never return.
