Borrowing from prime333's related thread, it appears that marriage isn't for everybody - a position that Statscan tends to support, since the number of people who never marry is increasing, and 40% of Canadians who do marry end up getting divorced.
And divorce sucks.
So, marriage: is it a good idea?
What are the pros and cons? Is it better to stay single forever?
If you do get married, what are the most important things to make it work?
What are the things that are most likely to make it fail? Is it really always women's fault?
Where is the institution of marriage heading and what kind of relationships are going to replace it in the future?
How about that polygamy thing? Polyandry? Polyamory?
What's the best way to go?
