Is OTHER wrong in the post ? POST : My Mom and I have been close forever.  She met my "stepdad" when I was very young, and he is a great father. Their 20 year anniversary is approaching, and due to my moms financial circumstances etc. They are only now marrying. I love them both very much and I'm glad to be there. 

My mom is VERY sentimental. Her favorite song is "Hallelujah" by  Leonard Cohen. My mom has struggled with severe depression through my (and her) whole life, and on several occasions in my adult life, she has been on the brink of suicide. I drive down to visit her and bring my guitar,  and every time I play her favorite song it brings her back to reality. 

She is planning her wedding as a surprise for my dad, and she asked me specifically to play this song at her wedding for them. Of course, I said yes.  This has been the plan for several months. Her brother is a minister and he is officiating their wedding, so it is a very personal and sentimental ceremony. She isn't having a large group of people. 

The other night mom texts me from a bar (a little tipsy) about a woman there doing Karaoke. She sent me a fuzzy video of a woman who I presume sings for a church choir belting out none other than Leonard Cohen's Hallelujah. I said it was very nice, and left it at that. 

The following morning Mom calls me up to rant and rave about the woman she met and how great her singing was. She then informed me that she asked this woman to sing the same song for her wedding, and asked me instead to just play accompanying guitar. This is about 2 months before the wedding. 

My feelings were hurt. I told her that, and she blew me off saying that I "probably wouldn't even have sang it". She then told me that I was just going to play guitar, and in a perfect world I would have sang it for her, but she knew I wouldn't. She started back peddling and saying she knew i had anxiety and wouldn't perform in front of people. 

Not only does that seem inappropriate to me, but I was in a band for several years and have played in front of crowds very often. It seems she realizes she made a mistake in how she worded this to me, and is trying to find a reason to justify herself.

I told her that i hope this woman knows how to play the accompanyment, because there is no way i would do it now. I didn't rescind my wedding attendance, and it wasn't a huge argument. She is now pestering me every time I talk to her, saying she wants me to sing, she didnt realize i was seriously going to play etc. Etc..

I know it's HER wedding, and I have no problem there. She can have this woman play the song,  but I was under the impression that there was some significant sentiment to me performing for her and dad.

AITA for refusing to play accompanying guitar for this woman?
