Gomen. Mitomeyou to shitakedo, yappa dameda.(I’m sorry. I tried to accept it, but I just can’t…  )

Omae ga aitsu to issho de iitte mitomerarenainda(I can’t accept the fact that you’re happy with him.)

Wagamama dakedo, taerarenai. Nanika warui koto ga attara iina tte omocchaunda. 
Aitsu to wakareryaii toka, aitsu ni furareryaii toka  

(I know I’m selfish but I can’t help it. I keep hoping that something bad happens. 

I wish you’d leave him or that he’d leave you.)
