Married couples usually get certain financial tax brakes from the government compared to single couples.
If you rent or own a house, $1k in rent can now be $500 due to a partner paying the other half
When you have kids, they can take care of you when you get older. Retirement homes have a high abuse rate.
Your less likely to get in feuds with the opposite gender since your girlfriend will usually ward them off. Essentially, no woman will fight you with your girlfriend around. It's basically a shield.
Also, sex is good for your health and stress relief.
