My boyfriend got me a puppy for my birthday and now I feel bad?

i turned 21 on the 20th of July and my boyfriend got me a 1.5 month old black lab puppy as a gift. i'm extremely grateful about it but i feel kinda bad that he spent a ton of money on such a gift like this for me. when i asked how much it was he said the puppy was $300, and the other things (kennel, dog toys, dog bed, etc) came to about $700 with taxes. i told and showed him I really really appreciate this gift a ton. the one thing that's bothering me is that he spent about a grand of money on me

i don't want to feel bad about it at all, but something is just making me feel like he spoiled me. how can i get over this?

by the way, I've always been like this my whole life; not liking when people buy me things because then i feel like I'm using their money
