So today's my birthday...

It's about 9pm here and my boyfriend of 2 years who I live with has not given me anything for my birthday. No card, no "happy birthday", no flower, nothing. He knows it's my birthday tho (mom called earlier to wish me happy birthday). I wanted to at least go out for dinner but he said that because I've been having a really bad headaches and nausea the last couple of days that it's probably best to stay at home and go for a dinner another day. I'm sorry if I sound pathetic or selfish but right now I'm feeling really disappointed and sad and lonely. We're definitelly not broke, our relationship's been working and everything and I would have even said that we're happy but right now I feel hurt... I need to go to bed in about 2 hours (getting up early) so I'm pretty sure nothing's going down tonight (he's in his office, working). On top of that, mom texted asking what he gave me and I just don't know what to say... I feel embarassed to admit I didn't get anything. I really don't feel like discussing this with him right now because I don't want to make it look like I'm begging for gifts here. I'm not, I just feel neglected and forgotten. Am I being selfish here because I expected something?
