Should I feel bad because he doesn't consider me a best friend? Even though I do everything for him?

So I met this guy like 5 years ago and we clicked instantly like brother and sister. Well I'm a girl and he's a guy. I don't get along with girls to much and I'm more of a town boy then a girly girl even thou I still act and dress like one. So I literally always pick up my friend when he wants to hang out he never helps for gas. Every time we go out to eat I always have to pay for him because he never has money and this is almost every other weekend. And I and like tonight were suppose to go clubbing we get en free but it's a club we always go to every other weekend and umm its 7$ parking I always pay today I asked him to help me with 3$ and he told me he would think about it or he'll see. So my friend asked him who is your best friend? And he mention his other friend rob who known only a year. Like I do everything for him when we hang out I always pick him up the other day his mom gave him 20$ and we was at the club and he asked if I wanted a soda then I said yes thinking he would pay but no he asked me if I wanted a soda because he wanted one but he just needed me to pay for it. Which pissed me off. And It hurts he wouldn't consider me his best friend. He has came over my house plenty of times and stayed the night. Slowly but surely I don't get him things anymore well I do sometimes just not as much as I use to. I mean I even invited him on vacation and he never stops to think of me only his other loser friends who have no jobs and spend all day in the park doing nothing.
