<human>: Could you distill the essence of the text into 1-3 sentences?

My boyfriend (22) and I (21) have only been together for 3 months. I wasn't expecting much from him for my birthday, but I was hoping for at least a card or SOMETHING. He showed up to a group dinner that I organized with a bunch of friends, but only paid for his own meal and left early. I only spent around $30 on his gift, but it is something I KNOW he'll like, and I put some effort into putting it all together. I am pretty bummed out that he didn't think to get me anything or do anything for me, and now I am not sure if I should feel awkward about giving him a present on his birthday.

Reddit, how do I address feeling unappreciated on my birthday without coming off as a total bitch/spoiled brat? And should I feel awkward about giving my bf a birthday present a week after he neglected to give me one?
<bot>: boyfriend didn't get me anything for my birthday, but I've already purchased something for his birthday (next wednesday). Should I be upset/ feel awkward about giving him a birthday present?
