Some thoughts -
I'm going to replace 'jealousy' with 'anger', because anger can be written about without sexual connotation, and sexual connotation has a way of triggering primal/instinctual emotions when discussed.
So some passive aggressive personality types have a pattern of doing things that -
1.) Anger a partner (or others) because the actions are aggressive, and...
2.) Done in a way that they can deny responsibility, the 'who me? I was just [fill in the blank]'
The passive aggressive type does get something out of this. One possible thing they may get (though there are other reasons), is if the partner reacts with anger, it's proof that the partner is emotionally involved. If that is a core motivation, and the partner doesn't react, proof the partner doesn't care.
The problem for the partner is there is no win possible.
If the partner reacts in an angry way, the passive aggressive type gets what they wanted, and so is reinforced, and more likely to repeat.
If the partner doesn't react, the passive aggressive type has the option of trying again, upping the ante, because why not? Apparently the previous attempt was 'A-OK', so they did nothing wrong, or at least not wrong enough to avoid repeating.
Unfortunately this is not a perfect comparison, unless the passive aggressive type also seeks out others (i.e., triangulation) who perceive the PA type as a victim, and sympathizes. Those who think 'How can you be angry with him/her? He/She is passive, not the type to hurt others, not someone to be angry at'
Again though no win is possible, because sympathizers really do believe they mean well, and haven't seen the aggressive side, only the passive opener. There is no talking them out of this belief, and until/if they are more deeply involved, they won't see that aggressive side either.
