In any relationship, it makes sense to use some sensitivity in deciding when and how to tackle a difficult relationship issue. There are ways to word a grievance that avoid making it sound like a personal attack, and if you mix in some appreciation you increase the chance that your partner will hear you. But with an abuser, no way to bring up a complaint is the right way. You can wait until the calmest, most relaxed evening, prepare your partner with plenty of verbal stroking, express your grievance in mild language, but he still won’t be willing to take it in.
