You've said it often, not just " before", and I do consider it to be a negative. Patty was not Ray's equal in terms of either life experiences OR education, and I don't see how she could possibly have interested him for 18 or so months. Usually, a very intelligent person has to have a partner who challenges them in either life experience OR has a similar high intellect and challenging career path. This is not specific to Ray and Patty, but is psychologically true of mature couples in general who have dynamic relationships over a long period of time.
I think he was, as a few posters said and one commentator remarked, " coasting" until someone else entered his life. Maybe that someone else DID enter...and his life plans changed. We don't know.
Did I mention that the words " boredom" and " trapped" were used by other posters very early on to describe some interview summaries with people who knew Ray and Patty? One of his friends said he was a very good D.A., but his personal life was the equivalent of a " pet rock". I don't know who said that, but the posters here took it as a slam against him just a few days after his disappearance and before they knew what a co-dependent set of multi-factorial personal life circumstances he was in with Patty. I think the guests who knew Ray were mostly on Greta's TV show. Also, some of the behavioral therapist type talking heads talked about him leaving due to not having anything significant emotionally keeping him there..
Once people learned the facts about her background, the talk increased. No one ever said " He was too old for her", or " His career was too dangerous" but said " He must have been emotionally recovering from his second divorce" and " Patty was hurt by his disappearance but never ONCE pleaded for a kidnapper to release him; instead asked HIM to come home". I think that speaks volumes of what she was thinking. It was also hypothesized that they had a falling out of sorts because the situation between them had become such that he had pretty much promised her a commitment in actions, if not words, OR she perceived thus. The paying off her mortgage then living with her and not maintaining any separate residence, him driving a car owned by her and with HER name on the vanity plates, and then of course the job situation in the same offices.
They were intertwined in all aspects of their lives.
I started thinking today more about how bored he might have been with her. Besides, there is that photo of her standing next to Lara's mother which speaks louder than a thousand words to me, personally.
Most of all- when Ray had been missing for a short time, and the family was still attending press conferences, what on earth caused Patty to ASSUME that Ray was in a position to be able to leave at will and then return to her at will? She pleaded with him to " Come home" but she never pleaded with a possible kidnapper to release him, to not harm him, anything of that nature.
Several posters early on said they thought he was using the excuse of excess tiredness and sleeping as a temporary emotional escape. I think there is a great possibility that they were correct, and have thought the same for years.. either that, or he was doing something on his computer late at night on some nights before he disappeared, thus was napping during the day out of choice and Patty didn't know the whole story.
