Betrayal

Like to start with the pro.
Amazing ending and a great first stanza.
The poem is seem to me like an emotional poem, however, There are some brakes in the lines that just disturb the flow of emotions from poem to the readers heart. Finally, I fell that the fourth stanza seem a little bit odd as it does not provide a smooth transition from the third to the fifth stanza.

It's as if you wanted to write a rhyming poem but your emotions demanded less structure and more emotion. I'm not sure if this is intentional or accidental but isn't that the result you are seeking? lol In keeping with that premise you could abandon quatrains and add emphasis something like this :

And so the truth comes out
After months of wondering
You want out

There is no doubt

You asked for commitment
A lifetime together
Who knew It wasn’t forever

Now you’ve changed
Your mind
Isnt that cute
The point is already mute

Story of my life,
Nothing new

Still can’t get a reason
Out of you

No worries
No need to shout
Just pack your shit
And get the hell
out
