Am I being selfish?

So my fiance and I had a big fight today. We've made up and agreed to put it behind us, but neither one of us has admitted we were wrong, and I was hoping for opinions.

I have been getting into running, doing it steadily for over a year now. Back in very early August, I signed up for a half marathon in Trenton New Jersey. It gave me exactly twelve weeks to complete the Hal Higdon training program I chose. When I signed up for it, I did mention it to my fiance, I told him it would be in November, and I told him it would be in Trenton, New Jersey, which is about an hour drive away from us. He knew I wanted him to come out and support me, and at the time, he did not make an argument.

However, now that the half marathon is this Saturday, he's been steadily bitching more and more about it, culminating in our fight this afternoon. He is a band teacher, and during the school week, he travels to three different schools. The job stresses him out. When he comes home after school, he wants to relax and play video games. During the weekend, though we sometimes go out to dinner or for a brief shopping trip, the vast majority of Saturday and Sunday he wants to spend in our apartment relaxing.

His biggest complaint, the one that truly triggered our fight, is that he's "wasting" one of his two weekend days. He says we're going to have to spend a grand total of three hours driving, and around 3 hours at the half marathon itself, which "wastes" a minimum of 6 hours of his Saturday that he could be spending relaxing. His next complaint is that he's going to be alone for those three hours while I'm running, and he's going to be bored. That makes his Saturday not only wasted, but boring. Then, he complained about the gas money we're going to have to spend to get there, at least 20 dollars worth, and money is kind of tight (yet, he always has money for video games....). Then, when I brought up how much I spent to register for the half marathon in the first place, he completely blew up and flipped out at me for "throwing away" 95 dollars. Granted, this 95 dollars was MY money, but he's been paying the vast, vast majority of our bills because I've only been able to get part-time work lately. He claims that the 95 dollars could have been put to much better use. I didn't bring up how much he spends on video games, because he does pay the majority of the bills, and he should be able to splurge a bit.

I told him that I haven't bought myself anything worth more than 5 dollars in a year and a half, no clothes, no books, no entertainment, nothing. Yes, the 95 dollars could have been better spent, but if it was the only thing I was splurging on in a year and a half, I didn't think it was that unreasonable. I told him that I've been training for this event for 3 solid months, and I didn't think he should count his Saturday as "wasted" because he was coming out to support me. I told him that yes, he'd be alone for 2-3 hours, but I'd gone to concerts for him at his schools to support him. The total numbers I have spent supporting him at his concert is easily more than 20, and I've never asked him to support me before.

What upsets me the most, and that I told him upsets me the most, is how much he's been complaining about doing this. I can understand that he doesn't want to go, it's not exciting for him, but I want him to do it without complaining. When he rants endlessly about what a horrible inconvenience it is, how boring it's going to be, how it's the last thing in the world he wants to do on a Saturday, it made me feel awful. I asked him to please stop complaining and ranting and raving. He said he had every right to complain because I'm asking a lot of him. Finally, I snapped at him to just not come, that I didn't want his support if he didn't truly want to give it. He said no, that he wasn't giving me "something to guilt-trip him about later" (I have NEVER guilt tripped him) and that he was definitely going.

He then ranted that I handled this event completely wrong. That I should have told him from the second I registered how much I was paying, where it was, exactly how much of his day I would be "wasting". I should have done this and given him a chance to say "no". Then he told me that if I wanted him to support me, I shouldn't have been selfish enough to do it during the weekend, when he only has two days off from school. I should have magically found a race that was closer to us, so he wouldn't have to drive as far, and that took place during one of his school breaks so "wasting" a day didn't matter as much. He told me that I was being selfish, asking him to do this so that I could run in a race.

I don't think I'm selfish...but am I? Am I selfish asking him to do this for me? Am I selfish for spending the 95 dollars on myself? Am I selfish asking him to give up one of his days off because I want someone to support me while I run?
