Undecided Question

Is this too offensive?

I have written a poem.. It's about my mother who left me when I was 9 months old, do you think I don't have a right to be saying these things aimed in her direction.. also, she left my father for another man, she was fit and able to do motherly duties, I think maybe she was just too young, as she had me at 19

A soul so pure, a mind so young,
Secrets and lies, the story unsung,
A mother figure walks away,
Invite the confusion, let it stay,
Grow on your own, never understand,
There’s no protection, no helping hand,
Exhale your breath, then suck it in,
Accept the rejection, let it crawl through your skin,
Are her tears of sadness, or of pure guilt,
Your respect for her, till this day does wilt,
Close your eyes, imagine the past,
These feelings of resentment, surely won’t last,
The more you think, the more you care,
But to see her hurt, you cannot bare,
She doesn’t know, when you’ve had a hard day,
When you mind is full of hatred, sadness and grey,
As you grow older, the more about life you learn,
These feelings grow stronger, continue to burn,
Still as an you can’t figure her out,
These thoughts in your head don’t cease to shout,
And they scream so loud, and ever so true,
It is as simple as three little words,
I blame you.
