Is it wrong for me to feel this way

Destiney

So my 21st birthday was the 15th and little backstory me and my boyfriend have been together about a year and it’s the healthiest relationship I’ve ever been in.I spend about 1k on him for his birthday in September I got him a room in Atlanta took him out to eat got him hundreds of dollars in gifts I got him his favorite Candy’s, a nice chain necklace, a peanut butter cake that he loves $250 worth of ballon’s etc etc well the 15th was my birthday and he didn’t take my anywhere or get me a card or anything and I’m not materialistic at all in anyway but I did feel forgot about and like I wasn’t important all I got from him was a happy birthday I was with him on my birthday but because we pretty much are always together now…but I’m not sure how to feel…I feel forgotten…how would you guys feel? He’s always been the type to provide and give and spoil me so it just doesn’t seem like him and he’s definitely not the cheating type but I’m not sure..any advice.
