Learning Curve

When our moment vanished like a morning fog
My jealousy grew like moss on the rock
That was once where we shared our first kiss
And carved out in stone our initials in bliss

Now you offer me nothing more than a smile
Not even a kiss on the cheek for old times’ sake
I guess friendship after is just not your style
I was your learning curve, I was your mistake

I know there is another man who could give you
All the things I was not able to accomplish like a fool
A warm home instead of a half empty house
To build a family, to call him your spouse

The thought of you together drove me to the edge
But I repressed all my spite and crazy jealousy
To congratulate both of you while hiding my urge
To hate him with fire cause he makes you happy

Now you offer me nothing more than a smile
Not even a kiss on the cheek for old times’ sake
I guess friendship after is just not your style
I was your learning curve, I was your mistake

I guess he won the battle of the hearts long ago
But I know you still think of us when you are alone
Because I am the only one who made you feel special
But I lost that privilege like some poor dumb devil

Now you offer me nothing more than a smile
Not even a kiss on the cheek for old times’ sake
I guess friendship after is just not your style
I was your learning curve, I was your mistake

I could just picture it clearly.

Wow! I'm speechless (in a good way).

Thank you for the feedback

I love it when someone admits to being jealous!

I am not sure as to how I should respond to the following line: "But I lost that privilege like some poor dumb devil." It seems to be a bit out of place.
