<human>: Can you condense the text into three sentences or less?

She loves the opera, and I can't stand it. I really do make an effort and go with her, keeping an open mind. We can only go occasionally because tickets are expensive! (can be several hundred dollars). We've been together 2 years

There's a particular one that I really can't stand that I've seen before, and I've told her this many times. Last week, she goes to watch it with some friends and I declined to join them. Afterwards, she tells me how badly she wanted me to be there and that it was important to her that we go together.

We had a big fight over it afterwards. I don't know why, but this really set me off because I've truly made an effort to enjoy her hobby, and I specifically told her I did NOT want to see this particular one.  I feel like if my presence is that important to her, she should have chosen a different one to watch (almost any other one!). When I declined, it didn't seem like a big deal to her. She never pleaded with me or anything but now suddenly it's a big deal.

I'm not quite sure where to go from here. Do I need to make a bigger effort in enjoying this?
<bot>: She goes to watch a show I specifically said I don't want to watch and gets mad after. What should I do?
