I'm obsessive about the look of my potential girlfirend/wife

I think im self sabotaging myself, it seems as though as i get older i keep coming up with different standards for the cherished possession that i guess is supposed to be my girlfriend. i've turned away what i'm now starting to realize were pretty beautiful girls for the most silly reasons and i don't know why. There was one girl who looked a little like a pre-2013 miley cyrus who pretty much followed me home, and i kept blowing her off because i thought a two year age difference was too much and told her that i wasn't interested. there were other occurrences in the past few years with even better and better looking women fawning over me and i'd come up with excuses like, well she has a nose ring, she has a tattoo, she behaves immaturely. I don't know, my standards used to be normal but now they are just a bit out of control. This year I've hired my standards even more, where all women i date must come from Europe directly and in particular from the countries of italy or france (different criteria for other ethnicities).

My tastes are getting a bit ridiculous. I've turning myself into someone who practically going insane obsessing over the desired aspects of a woman that doesn't exist! my dating luck has drained as a result of this and im starting to think this insanity is ruining my life, is it normal that i'm so obsessive over the women who i date to the point where i have a specific prototype of what our kids should look like. I want my daughter to have a a particular look and for each woman i look to date i make sure she has the characteristics that will lead to that look. I can't control my mind to get it to stop thinking in this way.
