First question: Main storyline is as follows - noble guy falls for a member of the lower-middle class (who is also a magician, and his father doesn't like magic), refuses to call it off, father disowns him and cuts him off completely. He has a small amount of money from his late mother, but needs to begin working in order to support him/his lower-class lovemuffin in a manner that, while it may not be nearly as grand as he's accustomed to, will at least be more comfortable than living in a working-class neighborhood. What kind of well-paying professions existed for men who were well-educated but not in a specialized field (ie: he has not trained to be a doctor or lawyer or something similar)?
Second question: What sorts of endearments did Victorian couples use for each other (assuming their relationship was actually based on love, that is)? Dabbling in the Sherlock Holmes fandom has cued me in to the usage of "my dear" or "my dear man/boy/fellow/[profession]/[name]", but since Watson and Holmes use them on each other, they strike me as less particularly romantically intimate and more indicative of fondness or emotional closeness, like a weird Victorian way of calling someone "dude". Is that true? What would people use?
Attempted searching: Googled all sorts of variations of these, as well as nosed through Victorian letters/love letters where I could find them, and tried the Dictionary of Victorian London.
