Treat you better shows us about the things that are left out in the past,that can't be reversed.
The song has gotten more than a bilion views and it really deserved it.
Shawn Mendes says that he can treat his ex better than her new bf.
That's what this song is about.
But if he can treat her better,then why the hell did she left him.
Maybe she doesn't wanted to be treated that goodly.
Shawn is really going through a phase,the breakup phase.
She dumped her.Obviously.
That's why he sings this song.
But thank god that she dumped him,
That is why we got an amazing song to hear.
I think that its time to move on Shawn.
If you listen to this song's lyrics very carefully,then
you can find that this is the same things that go through our head when someone dumps us.
And we all know that what happened in the past can't be fixed.
There is no use in thinking about all those things now.
You have gotten a billion viewed song and be happy about it.
At least you have gotten something of use from your breakup.
People like us have gotten nothing like this.
