My GF is upset that I don't like Attack on Titan

I just wanted to say that I know it's not a big deal but it's enough to be annoying.<br>My GF is a huge Attack on Titan fan, however, I don't really like the series. I have watched 2 seasons of it and I don't like it. The reason is not important to this post.<br>The thing is, that she knows that I don't really like the series but somehow she always tries to make me watch it. She always makes arguments like "if you watch more you will like it" or "you just need to watch more it will get better". I told her multiple times that I don't like the series at all and I don't want to watch it anymore. She also says that I have to give it a fair chance and that she also watched anime she didn't like because I asked her to. And the thing is that she also didn't like it and she said "I won't watch it again".<br>I think the issue here is that she wants me to like the series because she likes it and she wants to be able to talk about it with me. It's not that I hate Attack on Titan, it's just that I don't like it and I want to watch other Anime with her. I want to mention that we have been watching anime together for 19 months so it's not a big issue but it still annoys me to this day.<br>Sorry for the grammar mistakes I'm not a native English speaker.
