To add to your points, I will say he should ask her what his stand his if after employing the above and things are still indifferent. It won't be nice to give up a slight annoyance, love worth fighting for, the lady may have something to say which he doesn't know. He should try again to do what you said and take the bold step of asking her what she thinks of him if she's not willing to concur.
