Is OTHER wrong in the post ? POST : Throwaway bc my mom will occasionally go on reddit and not log out of mine. This was about a week ago.

Tl;dr at bottom

So some context. My girlfriend lives in Germany and I live in the United States. We have been dating for about a year and a half. Anyway, so I decided to stay for her birthday. I stayed there for about 3 weeks. I left 2 days after her birthday. I did not plan on getting her anything considering this was kind of an expensive "gift" of my own. I didn't surprise her, this was planned months before it had even happened. So the day of her birthday, I decide to take her out to eat. We spend the whole day with each other, and then there was a party at her place. A small get together you could say, but nothing too big. As we get home and get her house ready, she asks me out of nowhere, "Soooo, what did you get me?" I look at her kinda perplexed. 

Me: "Um, what?" 

Her: "My birthday present?" She says laughing, but very serious.

Me: "I thought me coming to Germany for you would be a gift enough." I was super tempted to bring up how much the ticket was, but I know it would make me the asshole by default. 

Her: "So...you didn't get me anything else?..." Her heart dropped. Like her whole world was shattered.

After an awkward and silent party, we argued for the better part of an hour in her room. Saying how she was under the impression I was going to get her something. Anything. She hasn't been dropping any hints at all. No "Wow, this purse looks soooo good." Or any obvious signs a man would've picked up. 

Am I the asshole? Should I have gotten her a gift? Was I right not to? Thanks for reading. Any questions you guys have, I'll try to answer them asap. 

Tl;dr: Went to visit my girlfriend in Germany and stayed for her birthday. Didnt get her anything because I thought me coming to visit her was already a big gift. She insists I should've got her something. I say I shouldn't have.

I am on mobile so forgive me for the bad format.
