Hello, personally I felt that the memorial really conveyed little about what jws really believe. It is designed for those jws that believe they will go to heaven when they die and be kings and priests in God's Messianic Kingdom. There are 8 million jws worldwide and only 14,000 plus self-proclaimed partakers of the bread and wine. With over 111,000 congregations worldwide, most congregations will have no one partaking. The rest are said to have the hope of living forever on earth in paradise.
Many times the talk has few mentions of Jesus so it is called the Reject Jesus party.
The number of attenders will seem large, but inactive jws, disassociated, disfellowshipped, and non-jw family (like you) and students and other unbaptized attend. Many only attend this one time yearly.
People will be very friendly seeking out new people, especially the elders. In the various congregations I have attended this was about the only time I was noticed and greeted by an elder. In your case, you are a prospective convert and you can get more attention that the average jw who has been attending for many years.
The best meeting to go to is the Watchtower study which puts forward doctrines and policies. You can print off a copy for that Sunday from www.jw.org . I suggest you read it on your own and compare it with what you already know. That website also has WT publications back ten years.
My husband was not a jw when I married him. I wish though he had shared his doubts with me. Many times when he asked questions, the answers from the elders were less than truthful.
I'm glad you are trying to heal the problems you and your wife have in your marriage.
