My boyfriend sends me gifts often, but I don't think I have given him something once. I think he understands that I have no money and am paying my tuition by my self, and he hasn't said anything about it. Should I be worried that I have hurt his feelings?
I wouldn't. I'm not sure how long you have been with him, but if it's been awhile then I would think he understands as he's still with you. Obviously he hasn't broke it off due to this, and he hasn't brought it up, so I wouldn't think it's something that really bothers him. That being said, if you want to make sure, you could always just have a talk and explain that you appreciate and enjoy the gifts he's given you, and that you'd love to be able to do the same for him, but due to being strapped for money due to paying for your tuition you are unable to do so. If he has a problem with it after then, then he's obviously not someone you should be wasting your time with in the first place, as a healthy relationship needs understanding between both parties. I think if it's something that bothers you/worries you, it's always just better to get it out and make sure they understand how you're feeling and also understand why you're not able to, though you wish you could.
Another thing is you could always look at ways of giving something but not cost you a fortune. I'd imagine a card, either from a store or even printed off computer/handwritten with a nice note inside is something that would bring him joy. He obviously cares for you if he's willing to spend money on you, so a card is just a little way of saying you appreciate it and return the feeling that you obviously care a lot about him to. I always was one to give my GF's gifts, as it was just my way of showing I care and they mean a lot to me, but I personally never expected anything in return, and just a simple reassurance in a card of professing their feelings for me was enough to always make me happy. Simple, non-expensive things can mean just as much or more then some more expensive gift.
