I have no doubt you’re loyal, Unicorn, but Quinn doesn’t know that. Just as you’ve done extensive due diligence on him, it makes sense for him to closely at you and the potential live in situation—and to look at actions as well as words. Is it possible that Quinn took the pasta episode as a signal that you’ll be less generous than he wants? Have you discussed the specifics of your offer—specifically whether you’re offering a stipend on top of room and board?
Also, I get the feeling you’re smitten with Lindero. Do you prefer him over Quinn? Lindero may be sending flirtatious texts, but the relationship isn’t as far along as the current one. Once things get down to brass tacks, Lindero may be no less hesitant than Quinn.
