I am looking for a story where the one guy breaks up with his boyfriend because he likes to hurt the other psychologically. I can't really remember the story but I think the other guy said okay or something and then you read the breakup guys thoughts and hes waiting for the other guy to disagree or something.

Also any other stories with similar things( where one likes to test the other psychologically, only for it to backfire, only as long as they get back together though)

thanks

Hurm.... these are KINDA close... maybe?
Overdose
Scarlet
Both seme's cheat and to some extent I believe they are testing their partner's love for them

I think this fits, I really LOVE and recommend "Warui Yume" it's just a oneshot though, but it's my favorite, it's awesome!
