Need Maid of Honour Advice

So back in August 2018 I asked my best friend from high school to be my MOH who we'll call J. J is 26 and lives in Nova Scotia and I live in Ottawa, Ontario. This is a 1200 km (745 miles) distance. I told her right from the start the wedding would be in Ottawa in September 2019 and she would have to travel from Nova Scotia, which she was fine with. Now J has always struggled financially and doesn't have the greatest paying job, but she was adamant about coming and being Maid of Honour, even though all the traditional Maid of Honour duties have essentially been passed off only my sister and another bridesmaid as they both live here in Ottawa near me. I understand it's extremely difficult to plan a bridal shower or bachelorette party when hundreds of miles away, so while I'm sad she's not participating or planning them, I completely understand. However, she took almost 8 months to save $120 to buy her bridesmaid dress. This kind of made me raise some eyebrows in worry but she told me all year that as soon as she got her income tax return of over $1100 in April, she'd be using that money to buy her plane tickets right away and save the rest for activities before the wedding when she's here. Income tax came and she put aside only $100 from it, saying that she needed work done on her car and other bills to be paid. Okay, fine, things happen, she'll just have to kick her savings into overdrive. But now today she texted me and told me that her hours were cut at her job yet again, so her pay cheques are going to be even smaller. I'm genuinely starting to think she's not going to be able to come. She still needs at least another $200 for her flights alone, and she really only has 2 or so more months to save that up until the price of those flights start to skyrocket. It took her 8 months to save $120. I know it's not fully her fault that she's struggling financially, but I'm just so frustrated. She has had a year's notice. She assured me everything would be fine. Her boyfriend works full time so I have no idea why they're always so broke, they don't even have to pay rent. I'm trying so hard to not be an asshole but if she's not coming I'd rather just know now and not be strung along and given false hope that she is if she knows deep down she won't be able to. I might just offer her an out and basically say while I'd love for her to come and stay as my maid of honour, if it's causing financial stress to her and she's rather use this time to get her life together a bit more, I would understand. I'm just so sad and frustrated and (selfishly) angry.
