I found this link about passive-aggressive behavior that I thought that you might look into.
Hope that this helps a little.http://www.livestrong.com/article/14713-eliminating-passive-aggressiveness/
This is from Wikipedia:
Passive-aggressiveness (negativistic personality trait) is a personality trait said to be marked by a pervasive pattern of negative attitudes and passive, usually disavowed resistance in interpersonal or occupational situations. It was listed as an Axis II personality disorder in the DSM-III-R, but was moved in the DSM-IV to Appendix B ("Criteria Sets and Axes Provided for Further Study") because of controversy and the need for further research on how to also categorize the behaviors in a future edition.
By way of explanation on that point, "Straight Dope" columnist Cecil Adams writes:
Merely being passive-aggressive isn't a disorder but a behavior — sometimes a perfectly rational behavior, which lets you dodge unpleasant chores while avoiding confrontation. It's only pathological if it's a habitual, crippling response reflecting a pervasively pessimistic attitude.
When the behaviors are part of a person's personality "disorder" or personality style, repercussions are not usually immediate, but instead accumulate over time as the individuals affected by the person come to recognize the disavowed aggression coming from that person. People with this personality style are often unconscious of their impact on others, and thus may be genuinely dismayed when held to account for the inconvenience or discomfort caused by their passive-aggressive behaviors.
In that context, they fail to see how they might have provoked a negative response, so they feel misunderstood, held to unreasonable standards, and/or put-upon. This starts a new negative cycle, when the passive aggressive person "defends himself" from others' perceived stringent demands and retaliates with more passivity and unconscious sabotage. Impact of this behavior in the workplace can be considerable and cause some damage, because detection and remediation take some time.
Remedying this behavior can be difficult: efforts to convince the subject that their unconscious feelings are being expressed passively, and that the passive expression of those feelings (their behavior) invokes other people's anger or disappointment with the person, are often met with resistance. Passive aggressive individuals will frequently avoid treatment claiming that there is no way to remedy it.[who?] Since the effectiveness of various therapies has yet to be proven, these individuals may be correct.
Regardless of that opinion, Martin Kantor offers a treatment approach using psychodynamic, supportive, cognitive, behavioral and interpersonal therapeutic methods. These methods apply to both the passive aggressive person and their target victim.
Passive aggressive disorder may stem from a specific childhood stimulus (e.g., alcohol/drug addicted parents) in an environment where it was not safe to express frustration or anger. Families in which honest expression of feelings was forbidden, tend to teach children to repress and deny their feelings and use other channels to express their frustration.
Children who sugarcoat their hostility do not grow beyond it. Never developing better coping strategies or skills sets for self-expression, they can become adults who, beneath the seductive veneer, harbor vindictive intent.
Passive aggressive behavior was first clinically used in the context of "defying" authoritative figures. But noncompliance is not indicative of true passive aggressive behavior, which is the manifestation of repressed, self-imposed oppression of emotions based on a need for acceptance. Anger turned inwards that has no other way to heal or express itself will either turn into depression or passive aggression.
Signs of passive-aggressive behavior
The book Living with the Passive-Aggressive Man lists 11 responses that may help identify passive-aggressive behavior. 
* Ambiguity or speaking cryptically: a means of engendering a feeling of insecurity in others
* Chronically being late and forgetting things: another way to exert control.
* Fear of competition
* Fear of dependency
* Fear of intimacy as a means to act out anger: The passive aggressive often cannot trust. Because of this, they guard themselves against becoming intimately attached to someone.
* Making chaotic situations
* Making excuses for non-performance in work teams
* Victimization response: instead of recognizing one's own weaknesses, tendency to blame others for own failures.
A passive-aggressive person may not have all of these behaviors, and may have other non-passive-aggressive traits.
