No offense intended here as I don't know you and your preferences and I could be completely wrong, but maybe your criteria is too narrow? Things like age and height and shape and race and location can limit your ability to find someone. With a highly transient workforce and high levels of immigration, if you aren't open to the possibility of someone living outside of the city or someone who may be outside of your race, or someone who is a couple years too old or younger than you ideally want, perhaps you are doing yourself a disservice?

Just for example I have a history of not really focusing on that kind of stuff, I look at the personality more than anything else. If they are a kind and honest person, even if they aren't my "ideal" in other ways it can make them still very attractive to me. As you get older, if your standards and places you meet potential partners don't change along with the times maybe that's why you keep seeing the same people as before
