Maid of Honor dropped out and didn’t show up to the bridal shower.

I have been feeling really down and need some type of advice on how I should take my “friend’s” actions and if I should even feel bad about letting our friendship go. I picked two close friends to be my matron of honor and maid of honor. My matron of honor has been wonderful but my maid of honor has not been present at all. Just recently she sent me a text message this past weekend saying that she can’t be apart of my wedding. Needless to say I was hurt because I haven’t heard from her that much within the past 3 months. I would text her or call her about certain things some not being wedding related and she would either not text me/call bk or she would only text bk maybe a day or 2 later. She did text me once just to confirm that she purchased her dress months ago. For her birthday in March she booked a hotel suite and had a spa day, didn’t tell me in advance but had one of our mutual friends who was already there with her To call me and tell me about coming up there that evening to help celebrate her birthday. I couldn’t come bc I was having a birthday party for my son at the moment when she called me. She texted me last weekend apologizing saying that she could not attend my wedding because she loaned money out to other friends and family who has not paid her back and now she can not be in my wedding or attend my wedding. I told her I understood and asked if she will still come to my bridal shower, she never answered. My bridal shower was yesterday and of course she didn’t show up neither 2 of our mutual friends that I invited. I was very disappointed to say the least and feel as though she doesn’t value our friendship like I do. I’ve known her for over 15 years, since high school and had always been there for her no matter what. I’ve gone out my way to help her with anything that she needed help with or even just a listening ear. Now that I look back everything seems so one sided.
