How does Dating work in Buddhism What does the Buddha say about dating, in general? This is a fairly open-ended question, and any scriptural references would help. 
I would have lustful thoughts when I look at a pretty girl (though I try not to act on it and meditate on impermanence as I walk by her.) But, it just occurred to me that if I eradicate lust, then do I even need a girlfriend in the first place?? Thus, I'm really confused about how the mechanism of dating works. 
Is it even possible to have a girlfriend/wife without lust?
Or, is there an entirely different answer?

This question has been bugging me for at least a year, I would really appreciate anyone's efforts in helping me resolve this. 
Thanks! Answers with Scriptural references is preferred, but personal experiences are also welcomed. 

Praises to the Dharma!
A wise man should avoid unchastity as (he would avoid falling into) a
  pit of glowing charcoal. If unable to lead a celibate life, he should
  not go to another's wife. - Dhammika Sutta


A layman is not expected to lead a celibate life. What you are expected as a Buddhist is to avoid sexual misconduct.


  Is it even possible to have a girlfriend/wife without lust?


Yes, but not necessarily for the good. ex: marrying to get citizenship, marrying for money, power, marrying to cover up sexuality etc.

A good example would be a married man becoming an Anagami later. He can still live in the lay life, but girlfriend/wife will merely be ceremonial positions. He will just treat her as a sister or a friend.
