I feel resentful

So I met this woman and we hit it off really well. Long story short. We live about an hour and a half away from each other. I live in Houston area. We've had four dates and each time I had to drive to her neighborhood. I have paid for all of our dates and she has offered to pay nothing. This has been over the past month and we talk on the phone a lot and we have really great conversations that last a long time but it seems like I'm always the one that's initiating the phone calls and the texting and whatnot. But yet they're always seems to be an excuse of her not wanting to come out in my direction or at least even to meet halfway. I even offered to cook dinner for her at my place and she expected me to come pick her up bring her back to my place and then bring her back home. So we talk about relationships and she says that she wants a 50/50 relationship but yet we're not technically in a relationship because we're still dating as how she put it. I'm about ready to have the talk with her and just tell her that it's not working out because a) I can't afford her and b) I live too far. I'm curious to hear what others think.
