The Street Lawyer~everything going wrong for Micheal Brock

I am reading the book "The Street Lawyer". It is so far full of suspense,drama, and change in heart. One of the first things that happened is that Micheal ,the main character, was held hostage by a homeless man that went by the name Mister. After a while Micheal was convinced that Mister was not going to kill anyone. I believe he thought this because Mister was always falling asleep and only asked questions. He would ask his questions with no real point to ending then. It was almost as if  Mister was looking for a better understanding of something. Mister was fully prepared to die, kind of like he predicted his demise ahead of time. After Micheal's big event with Mister, he was changed emotionally. We find that he does not have a great relationship with is wife Claire because he mentions it a lot and we witness it in little things. When Micheal was finally rescued from Mister all of the other hostages where greeted by loved ones. Except Micheal, his wife was to busy at the hospital to come down and see if he was okay. Later, after Claire's shift was over we see the tension between them in their own home. They even have gotten to the point of leaving without any exchange of love or friendliness. Micheal asked Claire to just pick up everything and leave to vacation as almost a plea to rekindle their relationship. Unfortunately Claire coldly denies him and says she needs to work. Micheal then goes to see his parents, where she also denies to go to, and he again states that his relationship is working towards divorce. When he gets back no one is there to great him and Claire is gone. She somehow ''randomly'' decided to see her parents right as he was coming home. Micheal then decides to leave the firm which i believe might be for one of two reasons. One, This may be the last plea to Claire to try and fix their relationship. He might be trying to show her he has changed and that he wants to fix the issues and emotional strain they put on each other when all they do is work. Almost as if he is trying to put her before his career. Two, their failing marriage may be showing him he wants more. He was just through and emotional disaster, he wants someone to hold him and tell him everything is okay and get him back on his feet again, but without Claire to do that he is being pushed in a firm that was the first downfall on the marriage. Maybe he doesn't want to be in a place that is causing him so much stress and pain. Not only at work ,but also at home.
