My gf a while back organized a girls' night out to see the Billy Joel & Elton John concert with 5 of her friends. The concert is tonight.

One of the friends going is also my roommate's soon-to-be ex-gf. They maybe sorta kinda broke up yesterday. My gf had originally set them up.

One of the other friends got sick and can't go to the concert, and my gf couldn't find anyone else available to buy the sick friend's ticket, so she invited me. Partly to help her friend sell the ticket, and partly because she wants me to experience the show.

While it would be a cool show, I am hesitant to go for a few reasons:

1. The ticket was $110.
2. It's a girls' night.
3. Maybe I should be supportive of my roommate.
4. Maybe I should avoid reminding the ex-gf of my roommate.

I already talked to my roommate some today, and he doesn't seem too upset about the breakup. Kinda saw it coming and she was stressing him out.

So.......in my shoes, would you go to the concert?
