I left my girl back home
I don't love her no more
And she'll never fucking know that

from The Weeknd – Wicked Games Lyrics on Rap Genius

Meaning

Sets up the next line about him finding a new girl for the night

He doesn’t love his girl anymore, so he left her at home so he can go party, do drugs, etc. but his girl doesn’t know this. It’s like he’s cheating on his girl with this lifestyle that is no good.
