Cliffs notes: FI’s little sister is BM in wedding and she just moved to S. Dakota about month ago. Got text from her that she may not be able to come to wedding b/c of money. FI and I decided to pay for rest of dress and her father pay for plane ticket so she can come. We e-mailed her and called her to let her know not to worry about money no response back. Here’s the long version: My FI’s is very close with his younger sister she just turned 21. I think partially due to age difference he’s 13 yrs older and things that have happened in her youth have made him very protective of her (he and his father tend to baby her a lot). I also have a good relationship with her so I asked her to be a BM in the wedding. Everything was good fast forward about 5 months to August her boyfriend graduated from basic training and found out he was getting stationed in S. Dakota so they decided to have a quickie wedding so she can move there with him. I received a text from her about 3 day ago saying she is having money problems b/c she hasn’t found a job yet and isn’t sure if she can afford to come back for the wedding and pay off her dress. She said if we can help her out she’ll pay us back. I completely understand where she’s coming from so FI and I talk to her father and he says he’ll pay for her plane ticket and we will pay her dress off and no need to worry about paying anything back b/c we understand she's just starting out. FI e-mails her to let her know and calls her so do I all with no response back. Then I get home yesterday and FI tells me that FSIL has posted something entirely different on facebook for not wanting to come back.Here’s my questions is it bad if I keep calling her to ask if she’s coming not only because she’s a BM but because its very important to FI for her to be there or should I just say forget it if she comes she comes and leave it at that? My other concern is if I want to know b/c the wedding is one month away and her dress needs to be paid off soon so if I’m going to pay for it I want to know she’s gonna wear it.
