lifetime of a tie

My ties seem to suffer more abuse in a two piece suit. I'm upgrading my wardrobe and buying better ties. In the process I've grown fond of several ties. Perhaps I'm over protective, but I'd like to know if a waistcoat will help prolong the life of a few of my favorites. Any opinions? Experiences?

Thanks to everyone for responding. Click to see the tie Mulberrywood, to answer your question, I've worn the tie three times, and if you look on the bottom left, you'll see where some of the thread in the white dot is fraying. There are other spots on the tie like this as well. One of my other wovens, an XMI, has a much smaller amount of fray, thus my concern. My thought was that a waistcoat could lessen, or hide, future damage, as most of the wear is occuring on the bottom part of the tie. As I want to get a three piece suit next time, I'm also looking for a way to rationalize it, beyond the fact that they look nice. I'm not quite up to following AlanC and FIH's advice. I like elegant, understated dress, but can sometimes find myself seduced by the color and texture of a piece. In the end, I regret the purchase, as it doesn't match with what I wear. Buying fewer means that I force myself to think first.

It's something of a memento. I bought the tie when shopping with a friend. Said friend and I are several thousand miles apart, and the store is by them. Perhaps I've created my excuse to visit again. I thought that it might be bad luck as well, but I don't have as much experience with the wovens. I agree, and I'm getting there. The question is, how often will I need to replace each of the 50? Part of my goal in dressing better is to prove that it is not that much more expensive to dress well as to dress average. If you run the numbers (my professional titles have been things like "budget manager") I have a higher upfront cost with quality clothing, but it should even out over time. To give one example, when I moved from cotton dockers to wool trousers, I saved about $60-$80 a month in laundry service as I no longer need my pants pressed every day. That's real money, especially when you extend it out over the lifetime of the pants. Also, assuming proper care, those trousers will last far longer, which also equals a much lower cost of ownership. After my success with trousers and shirts, I've moved on to suitings. With the fraying of my tie, it caused me to ask if there is a value proposition to the waistcoat. And here I am.
