I'm So Alright, I'm Just Fine [own lyric]

this song I write for my ex-boyfriends
meaning of this song
:: I already move on and forget everything about him

Verse 1
I was happy found out this time I’m not living like hell
I’m over it, leaving you without a reason
I know it won’t be worse if I start from the first time
And it will be just fine if I’m better off

Chorus
This isn’t my life play around with you
My mistake disturb your fraud life
Back look when I know you can’t come back
because my fight isn’t with you

This isn’t what I want to be with you
I take everything back home with me
We are just one thousand miles ago
because isn’t promise I want

Verse 2
I can accept the thing aren’t belong to me
Like you say “I’m not belong to you”
Pray for the best for your future
But no one knew what’s the best look for us

Bridge
I take back everything I give damn to you
Try as far learn from my mistake
But this isn’t me, isn’t my fight
