In my KH we had JW woman who was single, never married, and available after Armageddon. She was very nice woman, and good friend with my mom. Both of them will sit next to each other and travel together. We even were together in 1991 assembly in Strahov in Prague. She always dressed with bright colors, unlike other elderly, single women who my mom called a gray mice. She had pink nails, red hat, beret, yellow to orange skits. Eventually she had a personal crisis after Strahov assembly, which even my mom does not know why. What I know, she did not have family either. One day she decided to jump in front of train, which run through my city. This train is more or less single car lorry, something like tram. She did not die as the impact catapulted her out, but she was disfigured and lost a limb. I went to visit her, she was looking out of window from wheel chair and refused to talk to anyone. She just stared away. Couple months later, she destroyed everything she owned, cut all pieces of her clothing, upholstery on her furniture, smashed all her china, and set the place on fire, while took sedatives, and died. I often wonder why she went the way she did. She did not deserved to commit suicide at age 60 or so. We could not even bury her, and she was cremated on the city expenses and scattered as she did not have anyone to claim the body.
When it comes to marriage, St. Augustine said that marriage is for these, how are afraid to sleep alone in the darkness of the night. Some people are happy to be single, and some people wants to be married. Many have unhappy marriage, and some people have great marriage. There is no rule what makes things better.
