Congratulations, you've lured a long time lurker into being a poster with this question.
My wife does, my best friend's wife gives none at all, but that's not what you really want to know. What you want to know is "will
she give
me regular blowjobs?" and the bad news is that no one on this board or any other can answer that question for sure, only she can and that still leaves the question as to whether she will.
From your story, it sounds like it might be a "shit test" especially if as you say she's "hot" and has been used for sex before, but that's only a guess based on your take (which is understandably biased towards that interpretation already). I also wouldn't gamble on "convincing her" to change her opinion; for every story about a guy who successfully convinced his wife to do something, there are at least a thousand who failed because we generally don't tell those stories.
Best advice I can give is to ask. Personally I'd lay it all out for her. Tell her that blowjobs are a must have for you, that you get the impression they're not something she will do but you're not sure if that's accurate, that since you've only been long distance until now you hope that's evidence enough that it's clearly not just about sex at this point, and that you don't want either of you to be unhappy going forward so some straight answers benefit you both: How does she feel about blowjobs? If she's willing to give them how often does she think is reasonable?
Use your own judgement and adapt to your style/circumstances as necessary of course but if it truly is a deal breaker for you, do your future self a favor and treat it like one instead of like a "nice to have."
Anyway, that's my take do with it as you will. Going back to lurking now.
Best of luck!
