Oomis’ point was that your requirement of external attributes in general changes over time- whether looks, abilities, etc. (or at least it should, to a mature person).
Also, it sounds like you have a fantasy in your head of what “the one” will look like. Most people have some sort of picture in their head, and they need to contend with it in order to find the right one- because Miss Right is not going to look like Miss Fantasy.
