This is a long article but I think it is interesting. It says one problem in marriages and relationships is that people tend to get bored after a while. It also says that over time, arranged marriages tend to be better than love ones because the people in arranged marriages spend more time in trying to make it work.
They also say don't try to change your partner but idealize your spouse to make it think as if he/she is better than he/she really is. And do exciting things together.
Since many of us are in D/s marriages or relationships, let me add my two cents worth. I think we are less likely to get bored in these relationships because they are more creative when you are doing things like giving or receiving spankings or bondage or being dominant or submissive.
I think the article is worth the read and will be interested in your comments and thoughts.
