Why would anyone want a long-distance relationship but have no plans on ever relocating?

Ok so I was chatting with some Australian man. He was sounded excited about starting a long-distance relationship, about how distance don't matter if there is true love and trying to fill me with too much BS. Then he asked for my opinion.

I asked several questions such as:

''So what are your goals, besides feelings, what do you look forward in a partner''?

''How long are we going to stay in that ''girlfriend and boyfriend long-distance relationship''?

''Do you realize one of us have to travel and move in'' or otherwise it's a fantasy?

He has no plans on ever relocating nor leaving his family (meaning I would), gave me a vague ''oh not so long'' answer on the 2nd question and kept trying to BS on love, trust and ''the moon and the stars'' talk. So what's the point?
