Of course it exists. A lot of people have been happily married for a long time. My wife and I have been married for 23 years. She's my best friend. There's nobody that I trust more.
The problem today is that too many young people are promiscuous. The more sexual partners you have the less you will bond with the one you love. Worse yet, every woman seems the same after awhile if you go that route.
