<human>: One of my close friends [mid 20s/F] who I [mid 20s/F] met six or seven years ago is getting married this spring. Her engagement to her fiance happened pretty quickly IMO- about six months after they started dating. Sidenote: regardless of my disagreement with the short time frame, he's a really nice guy, a great fit for her, and I really am happy for them as a couple. They really make a great team. 

Shortly after their engagement, my friend, we'll call her Becca, asked me to be joint maid of honor with one of her other girlfriends. She also decided to have a small bridal party, including two of her fiance's friends and the two of us maids of honor. Becca and her fiance decided on a wedding in Vegas to curtail expenses and to make things "simple". The couple really likes Vegas, so this made sense... not my cup of tea, but I've been supportive and enthusiastic about it for their sake. I've attended several dress fittings and dinner parties for Becca, having to drive several hours to her as she lives in another city.

Today, I recieved an email from Becca that had a spreadsheet attached; body of the email explaining that she and Steve have been "incredibly stressed" as of late and need help both planning, paying, and executing tasks for the wedding. In the spreadsheet, I'm named as paying for the DJ and splitting the cost of the decorations with the other maid of honor. Becca and I have discussed my paying for my dress, shoes, hair, transportation, and hotel for the wedding, and I've been on board with that completely... but this just doesn't seem appropriate. 

My finances have been tight this year, considering that the cost of living where I live has increased significantly and my recent raises at work haven't matched the cost increase. Regardless of my financial situation, am I wrong for not being willing to pay for the parts of the actual wedding? Am I wrong for thinking that grown-ass adults shouldn't get married unless they can afford it?

Give me a shortened version of the text
<bot>: Friend just asked me to pay for part of her wedding because she can't or doesn't want to pay for it on her own. Now I'm left with a possible blow to our friendship and a really awkward conversation.
