Can a current/prior USMC Staff NCO or Officer answer please?

My Husband has been a Marine now for 13 years, for the past 7 years he has been a Sgt. He has been passed over 6 times now (for reasons that the Corps would not share with him) and as you know that means he will be forced out when his EAS comes around. They put in for him to have an extension in November and he deployed in January with still no word on the extension. In March he was denied the extension. This meant he would be unable to serve the entire deployment and would be sent home at the half way point. In the mean time back at home I had been trying to get surgery scheduled for myself. I could not schedule this surgery with out knowing his home coming date. So he explained to his Msgt what was going on and that my surgery date depended on his homecoming. So we were told he would return in may. I postponed my surgery until the end of June beginning of july knowing he would have to spend close to a month on base before terminal leave began. Well when the 2 week mark came around we were informed that the may date had now been moved to June It was still early enough that my surgery would be ok. Also at this time we knew that we needed to find a place to stay for the few weeks we would have to be near base. So my DH asked Msgt if that was going to be a good date and he assured him it was. On this we put the money down on a place and I began counting the days till I would see my husband again. Well we are now 2 weeks out from our June date and we have now been told that our June date was never really given to us. My husband was basically told that he made up that date to tell me. I find it very strange that he would make up a date and then let me spend $1100.00 on a place to stay. This has now not only put us out the money but me out a surgery that I need because by the time we get home and I spend the time on antibiotics and the few preop things that have to wait till a few days before surgery I will not have time to get my surgery and then have my post ops before my husbands EAS and the end of our insurance. I have seen my husbands mental state change in the past few days as well as my own along with my health. We are both at our wits end and are not sure what to do next. Please if anyone has suggestions let me know.
