<human>: About two years ago, one of my cousins asked me to be a bridesmaid. Not my cup of tea, but we had been close as kids, and her part of my extended family has had almost nothing to do with the rest of us for several years. I thought, perhaps, I could be diplomatic and help mend ties. 

I went and picked out dresses with her, and bought my bridesmaid dress. Not terribly expensive, but I'm a college student--money is usually pretty scarce. Then she decides she can't afford the wedding right now, and postpones it. At that point, I'd had the dress long enough that the store will only give me credit for it. So, it's been sitting in my closet.

Less than a month ago, she called to say that the wedding is back on for June. Did not seem like a lot of notice to me, but whatever, I figured I would be done with the semester at that point, no biggie. She decided on *different* dresses now, but luckily the store would exchange the one that's been sitting in closet, I just have to drive down there and do it. 

We've had zero contact, except for a few texts/calls that were all strictly wedding related. We didn't talk at all during the time the wedding was postponed. At this point the whole thing feels like a huge waste of time.

I'm still willing to do the wedding--with any luck there will be an open bar, which seems like just compensation.

As for the bridal shower... I hate this sort of thing. I do not get the point. If I go, I will sit there, bored out of my mind, feeling awkward as hell.

The shower is in ten minutes; I live 25 minutes away and have still not even put on pants. I am thinking of calling and saying I got a flat tire. 

Am I a terrible person? What would you do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm supposed to be bridesmaid for cousin I don't talk to, and don't want to go to bridal shower. Do I suck?
