Polyamory

So our potential third didn't work out, after 4 years of long distance dating. Now the emptiness. Doing my job of chatting, searching, but finding girls in their 30’s who talk a good talk, but then crap out. Using an app called Polyfun, so they know the basics. But just today, I had to end the conversations with 2 of them. Both had the same issue. I need to be their king, and buy them flights to visit, plus gifts. Which I'm sure would be accepted and then they vanish. So I do not send anything online, and get grief about it. I don't knows if its generational, but these girls expect total one-sided relationship. I even told this last one, when she told me that I was “I want a king to spoil me, not looking to pay what he should pay”, that I was looking for a girlfriend, not an escort. Kind of mean, I know, but I just can’t believe the attitude.
Just wanted to share my frustration, I know poly people are a small percentage of the population, and finding someone willing to make a life change (we live in a remote area) is really needle in a haystack. But I keep searching. And hoping.
