I know that I am the asshole because I blew up on her about it when I should have been calm and should have stepped away from the issue. Don't judge me on that, because I could not have helped that part, but I still need insight on why it's wrong/right for me to feel this way.

I have known my girlfriend (20F) for four years, but we have only been dating for one year. She met my parents a couple of times, and we had a trip last Christmas break where she stayed in a hotel with me and my parents. It was a good time all around.

Half a year ago, my dad passed away. It was expected, but it still hit me and my mom hard. My girlfriend reacted to the news with shock when I told her. She was there for me when I was really struck by grief, but ultimately, she was over it just about the instant she heard it. I chalked it up to her not having known him all her life, but today, it really made me feel... aggravated.

A couple of hours ago, Stan Lee died and news got around. (May he rest in peace.) The moment my girlfriend heard, she broke down--crying in a way that I have never seen her cry. She was so mortified by this, and I sat down with her, reminded of the day that my father died and the way that I broke down. She started talking about Spiderman, her favorite comic book series. Stuff like how she couldn't believe that such a good man died and how she was going to miss seeing his cameos.

And for some reason, I couldn't help but wonder why she never said anything like this when my father died. Sure, she was there for me, but all she did was listen and tell me "I don't know what to say..." every time I talked to her about my memories. At the time, I accepted this.

Stan Lee is a media legend, sure, but she didn't even know him. My dad was someone that she sat down and ate dinner with. My dad was someone that she met, and she couldn't spare any tears for him. I was very upset. I told her these things, yelling when I said it. She stopped crying and looked shocked--and even in the moment, I knew that I shouldn't have exploded like that. We decided that we will talk about this tomorrow.

Look. Roast me. Tear into me. I feel very strongly about this, but I know that I might be in the wrong. I want you to tell me why I'm wrong so that I can gain perspective on this.
