Is OTHER wrong in the post ? POST : My SIL is going to be getting married next year and they have chosen to have a destination wedding. She just sent us the details, and it's going to cost us $2500 each to go. We hinted to her that we might not be able to go due to costs, and she totally freaked out.

For some background: husband is still a student and I am hoping to go back next fall. We both love SIL very dearly and have a close relationship with her, but we didn't even spend $5000 on our own wedding! It's going to be a big financial strain on us, and I don't know what to do. 

So, WIBTA for not going to her wedding?
