It was completely uncharacteristic of her character who had been ripping pictures of wedding dresses out of magazines since she was a kid and dreamed of her husband even longer.
Monica wasn’t scared of marrying Chandler, she had just realised she would never “fall in love” again. She would never have a “first kiss” again, she would never feel those butterflies that mark the beginning of every new relationship.
She was marrying one man and that was it.
Surprisingly, Chandler didn’t feel the same. He only wanted to be with Monica and no other woman, ever.

That feeling of only being with one person for a lifetime was not unique to Monica, and many couples on the verge of marriage have that same haunting thought.
Is this the only person for me, for the rest of my life?
One man, Dale Partridge, has written a stunning post, reducing many people to tears, on the beautiful prospect of being with one person.
But the father of three says you don’t really marry one person; you marry everything they grow and evolve into.
“I fell in love with a 19-year-old rock climber, married a 20-year-old animal lover, started a family with a 24-year-old mother, then built a farm with a 25-year-old homemaker, and today I’m married to a 27-year-old woman of wisdom,” he posted on Facebook.

"If your mind is healthy, you’ll never get tired of “one woman”. You’ll actually become overwhelmed with how many beautiful versions of her you get to marry over the years.
"Don’t say no to marriage, say yes and keep saying yes until the day you die."
The post has been shared almost 300,000 times with men from all over the world telling their stories of their wives and partners.
One user wrote, "Been married to the same old gal for nearly 40 years, why in the hell would many one want more than one woman. She has been all I want or need as long as I can remember".
