Answer:
The best answer to the question: Mark is in the _____ of the dissolution of his relationship, would be: Social phase.
Step-by-step explanation:
When two people end a relationship, or are in the process of doing so, there are a series of steps that they take in order to make the transition easier, and as little traumatica as it can be for each of the two involved. One such reaction, or step, comes when either, or both, of the partners involved in the traumatic event of breakup, start looking for support from the networks around them, such as friends, family, coworkers, and other people. This step is almost like a defense mechanism in which the person seeks to ensure support is on his/her side, so that the consequences of taking such a step as ending a relationship do not become added with the guilt of having been the one to cause the situation. Mark, is clearly doing this. He is garnering the help and support of those around him so that they understand what happened, at least what he says happened, and support his decision. This is characteristic of the social phase.
