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!
