Class and snobbiness

So I've been talking with a sweet, vanilla guy, that I've been enjoying . And then it turns out he is a fedex delivery guy. He wasn't exactly upfront with me about that, but my first reaction was that seemed like it would be a good fit with me. But I didn't want to be snobby, so I still planned on meeting him. He wants to teach karate. But he isn't yet a blackbelt, so it would be at least 4 years before that happened, and then he'd need the start-up money to get a studio. It seems like a very hard plan to have for a career.

But, then it turns out his ex-wife is paying him alimony. That totally threw me the wrong way. I could see being willing to pull more than half, but if it didn't work out, there's no way I would want to support him. They have no kids--why should she pay alimony (and yes, I would feel the same way if the genders were reversed. I can see alimony 30 years ago, and I can see it for a few years if one person helped the other through college. If Sarah worked as a secretary support Sam in college and then they split--sure, Sam can help Sarah get through college.) I've worked my butt off to get where I am. I work a second job around 3 nights a week to make a little extra. I love what I do, but I also made a lot of sacrifices to get here. He has sort of floated around, not committed to anything. Why should I risk supporting him? I know, I know. It would only be if we got married. And if we got married I could insist on a pre-nup. But if we got married, he would lose his alimony from his wife.

So, am I just being shallow here? My ex dropped out of high school, but he was more successful than I was and very smart. I was proud of what he did. It honestly was never an issue. Part of me thinks I should just be glad he's being open about this, but then I wonder if there's other stuff he hasn't disclosed. And the alimony thing just feels wrong to me.
