Please help :(

My husbands parents just told us that his mom is leaving his dad. His dad is verh upset but knows he will eventually be ok. My husband and I are currently in Alaska, where he is stationed in the military. Ever since we got together we said we would be moving back to Florida aftter his term is up (where my parents are) for better opportunites, jobs, and just better quality of life- and he never gave it a second thought. He was all in and excited to go to Florida.His father lives in Pa (where we both grew up) thats how we know it's not a good place to go back to. Right after his dad called and told us the news he immediately said, "i have to move to PA" completely disregarding anything we said about florida and without even asking my opinion.We had a little blow out and he's currently not talking to me.I have tried to be supporitve and acknowledge his feelings about the separation but he's just not having it.It it wrong of me to think it's ridiculous that he wants to give up our dream of starting a life in FL bc he feels the need to hold his dads hand? I feel like everytime something happens in his family he tries to be the super hero and puts everything else to the side- including me. Is it also wrong of me to expect him to put me and most importantly our marriage above all else!?! please help because I honestly don't know where to go from here :(
