I think you are using the wrong word. You probably meant to say:
Which do you prefer? Single life or married life?
@ SHL, Ah, but you are describing things from one perspective. The very nature of your job brings you into contact with a subset of people who are very unhappy in their marriages and this may give you a skewed view about marriages in general.
Ask someone who owns a romantic restaurant that is popular with couples celebrating Valentine's Day and Wedding Anniversaries and they could tell you about all the happily married couples they see. Maybe they would give the advice, "Yes, do get married. The people who are married seem so very happy!"
This brings to mind the story of The Blind Men and the Elephant. https://www.youtube.com/watch?v=Vn9BUfUCL4I
