Felling unbalanced, HELP!!! ?

I have the best bf in the whole world. He always buys me stuff cause he comes from money and i always feel so bad cause i can never get him anything. When we go out he ALWAYS pays even when i tell him i'll pay for my share. I got him a gift for his birthday and christmas, but i still feel so unbalanced. We're both 16. Is this normal? Would you feel this unbalanced?
