broke college student but bf wants gifts

hey girls. so i'm currently a broke college student yet somehow my boyfriend expects expensive gifts from me. and i just don't have the $. i also don't work while i'm at school because my parents want me to focus on school. lately he's been asking for an apple watch and making me feel awful cause i can't get it for him.. he does get me a lot of stuff but he's older and has a full time job. how can i make him understand i've tried many times! whenever it's a holiday i get him stuff like clothes sneakers a ysl wallet watches. i try my best and still it's not enough for him. i feel awful i'm sorry if this sounds like first world problems i just hate feeling like sh*t because of my lack of $. I wish he could be more considerate
