If you're giving the boy 3,000 baht a day - and, presumably, feeding him and buying him drinks as well, he's going to cling to you, literally and figuratively, for that reason alone. Such largese will make you glamorous in his eyes, on top of the purely economic factor. This doesn't mean he doesn't have any genuine feelings for you, but who can know - perhaps not even him. It's not a great place from which to start a long term relationship.

If you don't live in Thailand, I'd advise you to spoil him, enjoy his company, but make no promises of any kind. Not even to see him again. If you're in love, or think you are, you'll ignore this advice - and who knows, maybe it'll work out. If you do enter a real relationship, then it will not be a question of paying him, but supporting him (and to some extent, his family). If he expects a daily allowance which is more than pocket money, I'm afraid it's the folding stuff he loves, and not you.
