My [34M] partner [31F] didn't do anything for my birthday and I feel upset
We've been together for 3 years now and we've gone through the motions of a relationship. I always try to be proactive when we're together buying her flowers or doing gestures of gratitude like cooking for her and many other things. She can be affectionate sometimes as well thought it is a bit of a challenge because she said in her culture they're not really good with expressing words of affection or love because they usually just use actions to express that love. Only challenge so far is we do a bit of a long distance thing where she lives in a city 3-4 hours away from me so we kinda take turns every other weekend on who spends the weekend to whoever's city.
It was my birthday yesterday and I had to work that day. She booked a vacation from work for the week so she has just been staying at my place. She's a huge amusement park person so she thought about going to the amusement park today as the plan for my birthday. Before that she's used to going to amusement parks by herself. Records videos of rollercoasters and her algo is filled with a lot of them. She got home yesterday and acted like normal. I thought there would be something at all like a small gift or even a letter for happy birthday but nothing. Not even a cake. Eventually I had to organize where we were gonna have dinner. I even paid for dinner myself.
I just felt so upset. That the whole reason she just went here is for the amusement park and not for my birthday. That she just needed a place to stay for her vacation. I'm in my 30s but to me birthdays are sacred. I've seen older people burn out in life because they don't celebrate their life or are not with people who celebrate them. I think it would've been better if I celebrated by myself so I didn't have expectations from others.
How do I go forward about this?
