I remember I told my first boyfriend that a grown ass teacher was hitting on me, he said things atune to Mr.Kang and it hurt me so much to think he did trust me nor did he trust us to have a future, a couple of days later I broke up with him and he told me he had long wanted to break up with me too. I'm just ranting here, but just know that if your SO tells you those things either a) they have low self-steem and are a little stupid or b) they want a lasting relationship, just not with you.

Low punch but understandable. Once he knew the beginning of the relationship, the time he finally had the courage, trust and love to be with Cirrus, was basically a challenge to see how hurt he'll be looking at his ex-crush after the shitshow that was the blackmail, he's not gonna take any word that comes out of Cirrus seriously and is gonna resent him for the humillation he feels.
A slap is not enough. He needs a punch to the fucking face, what a selfish molesting jerk.
