The Lights Are On But No One"s Home
Someone that just gets you can be the most exhilarating experience. Someone that you can give your soul to and you are on the same level as is the perfect partner. But if you are not attracted to them then how can you be with them. The first form of attraction like it or not is a physical one. The second one is an intellectual connection. This is more deep but without the first connection will never be established.
You have to make a decision in a relationship. That decision is what to base your relationship on, physical attraction or your soul mate. Obviously everyone would jump to the same conclusion but it is not a realistic solution given that you are not attracted to your soul mate physically.
Which one would you choose? Bearing in mind that you could end up spending the rest of your life with this person. Would you want to stay with someone who you are not attracted to for your whole life? Or even stay with someone that you don't get on with intellectually your whole life. Neither is ideal but you could be faced with such a situation.
Love is recognition of equality in every form and that includes on an intellectual basis. If you are with a stereotypical woman that only wants to talk about who's getting fired at the nail salon, or who celebrities are dating then it may not stimulate your mind. You may want to talk about a global crisis, or a natural disaster. You can tell your girlfriend is listening but is just not interactively responding to the conversation.
This can be a huge turn off and you will ultimately seek this attention from elsewhere. Contrastingly the things that she finds important may not be important to you, and she will seek these conversations elsewhere. Ultimately you need to be on the same wavelength somewhat to ensure that your relationship is long lasting. If the lights are on and nobody is home, but the girl is incredibly good looking you need to make a decision. Choose correctly.
