So I recently was asked to be a bridesmaid in a wedding of a friend. A little back story, I pretty much feel like a cushion to this friend here recently that when no one else is around I'm the backup plan. I have always been there to talk her through her problems but when it comes to my problems all she can say is "wow." She doesn't fully help me or talk with me about them. Most of the time she leaves them on read and her excuse is she was too busy or her psychopath boyfriend read it. Which really bothers me that I trust her with personal info and he is reading the messages. I told her that too. Well anyways a couple days ago we got into huge argument that I couldn't go last dress shopping because I was busy. She flipped on me basically saying I was a bad friend and that she was so done with me. You can't just plan a wedding out of the blue in less than a month and expect me to drop everything to buy a dress. So she apologized the other day and asked me to be a bridesmaid. I was actually suppose to be the maid of honor but I got demoted because I couldn't go dress shopping. Lol. So she asked if I could use my amazon to buy stuff for her wedding. I honestly think the reason she apologized was for that.  So she could use me. After that I just kinda think it'd be best if I was a guest because I don't even support the wedding. The guy she is marrying is so controlling and is a psychopath. So with me not supporting it. I think it's best I am not in it. I feel like bad person for doing this to her but I just don't want any part. I'm not sure how to tell her without feeling like crap. 

I asked this question already, but the answers said that they clashed so I changed one of the bouquets. Both bouquets have hydrangeas now, but the colors are the same. (The damas have purple dresses so I didn't want to add pink or yellow to the bouquets because the colors would be too bold.) The flowers are for a Quinceañera, if you don't know what a quinceañera is-- think of it as a wedding instead (with the birthday girl as the bride and the damas as the bridesmaids.)
