Depending on where you go for your numbers the divorce rate in this country is around 41% for first marriages, 60% for second marriages, and 73% for third marriages.
Most common causes of divorce in no particular order:
2. Communication Breakdown
3. Abuse - physical, psychological, or emotional
What the hell is wrong with people!? 41% divorce rate is ridiculous and we should be ashamed of ourselves. If you have to get a divorce, then you didn't know the person you were marrying in the first place. Barring some tragic life-altering physical or mental accident, people don't change. If your spouse was an ass when you dated, then they will continue to be an ass after you get married.
The warning signs are easy to spot, I'm sure you've all seen them. The people and couples I think that are most likely to get divorced show the following signs: getting too serious too fast, really extreme in their descriptions of their love for the other person, irrational decision making, highly emotional people, people with mental or emotional problems, drug and alcohol addiction problems, and people who have been previously married. If you can't communicate with the person you want to marry about all topics (financial, health, food, children, etc...) then you won't be able to make it work in marriage either. If you fight all the time now, you will continue to do that in marriage. If your life goals and long term plans are at opposite ends of the spectrum, just ignoring this fact and putting it off to deal with later will not work. When it eventually comes up, and it will, you won't be able to resolve it any better and you will both end up being unhappy.
Pop culture has not helped any of this either. Songs and TV do nothing but mock the traditional nuclear family and glorify the hardships of single moms. Many movies are specifically geared towards a whole group of people living this great single life in their 40's after being divorced. It's a joke. Getting married and then divorced leaves you unhappy and broke. Why would you want that? People need to wise up and think more about the decision to get married instead of letting their hormones dictate their life. And here's a thought, if your friends and family that you have trusted your entire life don't like your potential spouse, perhaps you should trust their judgement and question your own. Bottom line is no matter how 'in love' you are with someone, at some point you need to think rationally about your situation and relationship and make sure that you are marrying the right person. Marriage is forever, at least in my book.
