Its my birthday

Its my birthday and it has been one of the worst days EVER. First Work, then come home expecting a gift and I have nothing. He takes me to eat and its all good and we have time to run to walmart and pick up my cake I wanted. Well in the process, SO decides that he needs to go to his friends house. Were over there til after 9. Everything is closed and now i have no cake or anything. I been real enotional leading up too today and I'm not sure why. He keeps asking whats wrong whats wrong. I'm grateful for everything and appreciate the meal but a birthday isnt a birthday without cake... :/nobody in this house told me happy birthday in person. I just feel like I'm all alone. :(
