My Fiancé Moved His Little Sister Into Our House, So I Left Him to Rot

In the sixth year of dating my boyfriend, he moved his childhood sweetheart into our future home just to cheer her up.

When I tried to kick her out in fury, he stopped me.

He yelled at me, "Avery, Chloe is just like a sister to me! If you act like this, how can I ever marry you?"

I replied, "This is who I am. If you can't marry me, then get the hell out!"

When I walked into the house, there was another woman there.

My boyfriend, Carter, was smiling softly, leaning in to take a bite of the cake she was feeding him. They looked disgustingly intimate.
