Just to make it clear this is not at all about the money but lack of thought!
I've been with my bf/dp (don't know which to use!) for nearly 8 months. In that time we've had Xmas (met just before) valentines, his bday and now this week mine.
He brought me a small gift for xmas (saw each other boxing day relevant why I add this further down ) I didn't get him one, as we'd been seeing each other for about 3 weeks and hadn't even discussed it. Valentines he stayed over the night before we gave each other a card the next day, didn't discuss if we were going to both just did it of our own choice . His birthday I booked a long weekend off (both had a childfree weekend) i got him a small gift when we went out shopping a few days before , another on the day itself as well as taking him out for dinner, card, small cake.
It has been my birthday this week, he mentioned a while back about getting me something and I did the usual you don't have to get me anything. He said he wanted to despite me knowing he doesn't really do birthdays. Anyway it turned out due to work arrangements I couldnt see him on my bday as originally planned, no set plans as to what we were doing, but I was going to go to his. No plans to re arrange were done and it seemed we were set to go Sunday just gone til this Saturday without seeing each other. I told him on monday i was a bit hurt he didnt think to see me at all before this weekend as it was my birthday, we sometimes see each other mid week, to which he was a bit surprised (maybe I needed to spell it out) so he came round last night and took me and my two dc out for tea, in his words to make up for it. BUT he didnt get me a card or present. The present I'm not hugely bothered about, neither of us have loads of money, but I did kind of expect a card at least. He gave me one from his parents at the weekend with a gift card in which was very sweet as I've only met them on 4 occasions and he must have told them I had a bday coming up. The only reason I can think of is that because I didn't see him on the day itself he's thought there's no need, but then i think about Xmas and how he got me a gift despite not being together on the day?!
It's just thrown me a bit and left me a bit 
For context, he makes me feel incredibly happy and loved. He has brought me flowers on several occasions just because. On 2 occasions when I've had a bad at work he's driven over 20 miles on his day off just to see me on my lunch hour, so he's not completely devoid of sentiment, but no card??
I feel rediculous for even saying how it's made me upset. I don't want to sound like a spoilt princess, and he has said before he doesnt like the whole "being forced to buy card's" but still. Do I mention it to him or do I keep schtum?
