My wedding is November 16th of this year at 10 am. My fiancee' and I announced our date in December 2012 and whenever family, friends, etc asked us our date, we gave them that. My relationship with one of my future SIL's is okay; not great but okay. I asked her to do a reading for the ceremony and for her son to be the ringbearer. She agreed. My fiancee' asked the same sister's boyfriend to be a groomsmen. He agreed. We rented tuxedos based on everyone who said yes. We finally mailed out the invitations last week. This past Sunday, the future SIL sends a text message to her brother, my fiancee' saying that she'll probably get to the wedding by 10:30 am because of work. I'm perplexed because I thought she would have cleared her calendar for her brother. Nonetheless, my fiancee' replies back that we're trying to start as close to on time because of limo rentals and the reception start time. Her response to that was we should have waited and planned our wedding for a later date so we wouldn't have to worry about finances. Now, not only am I perplexed, I'm hurt and angry that she would say something like that. The next day my fiancee' gets a message from the boyfriend saying he can't be in the wedding because he's working. Is this how my relationship is going to be with my in-laws? I thought weddings were to be a merging of families, but it seems were being separated and pulled apart. Any advice on how I should proceed is greatly appreciated.
