What Do Unhappy Legal Careers and Bad Romantic Relationships Have in Common?

When I was in my first year of law school, I met someone I very much liked, fell in love with, and connected with powerfully. She seemed to be everything I ever wanted.
 
We quickly started spending all of our time together, spent our summer together, and lived together the following school year. I went to a party with her after we moved in together. I noticed her throwing herself all over another guy there. I was astonished by what I saw and thought she might have been drunk. I pulled her out of the party, and we fought about it for a few days.
 
By winter that year, I realized she was involved with the guy, so I moved out. It was not a good situation, but a relationship I think a lot of young people have when they are confused about what they want. We ended up getting back together by the end of the school year and moving back in together for the summer.
 
The summer went well, and we were engaged in the fall. On the night of my engagement, after she accepted my proposal, she told me she had been involved with this guy the entire year from the time she met him at the party. I was devastated by this but continued with the relationship and the engagement—I was in my third year of law school then.
 
While you might be wondering if I lived happily ever after, I did not. A few months into my third year of law school, she was involved with the same guy again. She moved out, gave the ring back, and the ridiculousness continued. If you are wondering what happened next, by spring she was back, and we ended up re-engaged. She moved with me to Michigan for the summer and lived with me during my year-long clerkship.
 
The summer after my clerkship we were scheduled to be married in August. She took a trip with her family to the East Coast in July and met the husband of one of her aunt's friends, who she ended up having an affair with. She then broke off the engagement and wedding that had been mostly paid for and did not move to Los Angeles when I finished my clerkship.
 
I moved to Los Angeles and was very happy, but she kept calling me. She traveled to Los Angeles at her own expense several times and wanted to get back together and re-engaged. So we got together again, she moved to Los Angeles, and we got engaged. Within a year, we planned a wedding and scheduled another marriage.
 
We were finally married a year or so later in New York. It was a strange wedding. I knew it was not the right choice but got married anyway. I drank too much at the wedding—likely because I was so confused and conflicted. 
 
We were married and together for a little over one year. About six months into our marriage, my wife started spending a lot of time with a guy worth hundreds of millions of dollars. One day, I left for work and then returned to the house ten minutes later because I had forgotten something. I heard her talking on the phone about her affair with this guy—she was in another part of the house and did not hear me. She denied it and told me she had not said that.
