I'm looking for all games where you play as a girl and you catch your boyfriend cheating on you. I'd prefer games where you have the option to pretend it's not happening even though it crushes you.
oops my bad thought you wanted where the girl can get caught in her affairs, ok then look for nymphomania priestess (this one is in constant development, you can be a cuckold and/or cheat with other girls) and NTR loop.
