I would agree with Song ; any decent therapist will only treat the person in the room!
This is more true than you realize when you're in this kind of situation. I had a therapist who would say she couldn't diagnose other people in my life, and then diagnose them anyway (non-MLC issues) and sometimes the diagnosis would change based on how she felt that day. The problem with this is that no one goes into therapy and discusses all the wonderful things about their families. We go in and talk about all the garbage happening, so it's easy for a therapist to see dysfunction and disease when really it might be subclinical, or perhaps even quirks or foibles. Someone's worst day becomes their everyday to your therapist. Diagnosing someone not present is really not a good thing, trust me. Be thankful if your therapist doesn't engage with this.
That said, a big part of my personal battle (which many of you have read) is that the world at large doesn't accept MLC as an explanation for this kind of behavior. Namely, in our culture we have a strong belief that everyone knows exactly how to make themselves happy, and that our actions are all basically sequentially leading up to self-actualization and "happiness." The idea that we sometimes do things that make us miserable -- knowingly or not -- or that we engage in acts of self-sabotage, self-medicating, etc. is lost in the discussion.
The notion that H was self-medicating his depression **absolutely** rings true for me. He had very definite peaks and troughs in his satisfaction with life, and always needed a big "next thing" to pull him out of that trough. I think he landed himself into a pretty big trough and OW was the only thing that made him feel anything in that moment, and that felt like love. If you've ever battled depression (and I have) you might be able to relate to that feeling of anhedonia, and then the random thing that gets through it feeling like total magic. I'd like to say that H had a choice in doing what he did, because we always have a choice. But brain chemistry is very powerful, and I think it would have taken a supreme act of will braced with strong family support to make any other choice than what he did. Neither of those things were available.
Personally, I wouldn't stick around with a therapist who didn't acknowledge multiple possible causes for someone creating a path of destruction through life. I don't buy into this idea that we all intrinsically know what makes us happy and are able to pinpoint it and pursue it. Humans are a lot messier than that.
ETA: The individuation issue rings true as well. Some people go through the first part of life completely unquestioning, aligning their actions with other people's expectations. They never stop to really consider whether they want to get married, have kids, etc. -- they do it because that's just what you do. In H's case, I think his parents disapproved somewhat of OW when he dated her as a teenager. Meeting her again later in life was an opportunity for him to commit the ultimate act of rebellion against his upbringing and do something entirely self-serving. Most people do that as teenagers and complete that phase of their personal development, but for others, they find themselves years later living a life they've never actually **thought** about because they just followed the crowd.
