Okay, so I need advice, one of my friends "Z" and this girl "Nen" started going out a couple months ago. They have a very strange relationship, Z always uses logic and if he thinks he's right he never backs down and Nen doesn't like conflict so when she backs down and doesn't argue her point back, Z feels neglected like she's pulling away from him and that she doesn't want to open up to him. Then Nen is all confusing I can't even understand her myself sometimes, like Z is really nice to tell her when things are inconvenient for him (I.E. her leaning on him and hugging him when he's trying to eat) in the nicest way possible of course, but then she gets passive aggressive and says things like "Fine, I guess you just don't want to be close to me" and neither me nor Z know if she's joking or not.

I can't convince him to break up with her if she treats him like that when he goes out of his way to be with her and has at one point got fired from his job to spend more time with her, so I need a really nice way of telling her that she should just treat him better. >.<
