just bothers me

I'm not trying to be snobby first off. My bf and I are long distance and my birthday was in January. He said he would fly down to celebrate and all well he couldn't. It's now march and we haven't seen each other. I don't require a gift or anything but I am upset that he didn't really even acknowledge my birthday. For his I took him out to dinner, got him several gifts and a picture of us. I just feel like I put so much effort into making his day special and I get nothing to show he cared about me. When I see him do I bring this up? I know for a fact he got me nothing not even a card. I just wish he cared even to send me a card I would have been the happiest girl. What do I do? Should I tell him how I feel? I'm not materialistic at all I just want to know that he cares. For his best friend at school who is a girl he got her a birthday gift. It's just that he bailed and forgot about me.
