Is Calvin not allowing Rita to use IWNLYD on the album?

No

Just other 3 songs

omg this is legit evil of him. why is he so pressed. how did she break up with him? im not even a big Rita fan but my God trying to run someone's professional life after a break up is evil

the only person who put work and effort into those songs is calvin SIS, seeing how he can just give them away easily means they are HIS songs and he did 95% of the work, otherwise Rita probably could've put up some sort of fight

i'm under the impression she used him for songs/success

I love them both so I don't know how to feel about this.

He's obviously a little bit bitter over the break-up. He shouldn't let his personal life & feelings affect his career decisions. It seems unprofessional & kinda tacky for him to take back tracks that they worked on together. :/
