My boyfriend thinks I'm rich. He always want me to pay everything during dating and living. what can I do?

So, my Turkish boyfriend is 28 and he doesn't have work. We live together and he always say me to buy foods, transfortation fees, and everything. I am 19 Japanese girl. I don't have work and I am not rich at all. I care money because it's my parent's money but he asked me that why do care I about money and that I'm rich so bla bla bla. I had my birthday and he said me he'll buy anything I want. and I wanted a necklace which price 100$ but he said me No, and he said mhe can buy this which is 10$... After that, he said me he want 1000$ wrist watch in his birthday...
