I'm sorry to say, but I don't think he sees you as family or a friend. It sounds more like he sees you as a personal ATM and somehow that you owe him something since he expected you to come back tomorrow. You have been overly generous with what you've already done for him; someone who appreciated it would be thankful, not demanding more. I worry that you might romanticize or "rose-colored glasses" situations and relationships and give people more allowance than they have earned. This guy straight up took advantage of your good heart within minutes/hours of meeting you. He is neither friend nor family and you deserve respect. Keep your chin up, the world needs more inherently kind people like you
