You met your boyfriend's mom. She never approved. She manipulated you with a lie that she has cancer, for you to break up with your bf (Ash)

He asks worried & say "why did you meet my mom?

You tell tell "Let's break up". He was confused.

After a argument

At last you lie "I got money from your mom to leave you". He doesn't believe it but you insist you did.

he was sad & angry "why you still need that" he grabs the pendent he gifted you & threw it across the bridge
