Must?
No. It had to be that way in my case because I'd decided to never marry before I went on that first date with my wife. Had I not felt that way, I would most likely never have married. I don't believe you love your wife any more or any less than I do. I can't know that, nor is it any of my business. If I try to articulate what I think about marriage it would be that I could not imagine, personally, getting married to anyone whom I did not feel about the way I feel about my wife. And that really did happen to me only once. That doesn't mean a damned thing for anyone else.
Interestingly, my wife doesn't understand this aspect of our relationship at all. She claims she still can't believe how certain I was so quickly. But, hey, it'll be 21 years in September, so I guess my "method" worked - for us. ;-)
It may well be the case that no one came to decide whom to marry the way I did. I don't know - guys usually don't talk about this stuff ;0)
