Gay Married Couple

We are a legally married gay couple in the United States for 5 years ... 16 years together.  He is was born in the Philippines with entire family still living there.  He came to the US at age 35 and is now 55 years old and been gainfully employed the entire time.

    I am 74 years old and have been a US citizen all my life.  I am a former CEO, currently retired, and spend my retirement writing and lecturing periodically after a successful consulting career in my later years.  I was formally married, but my wife passed away in 2008.  I have 2 grown children and 3 grandchildren who are totally supportive of my gay life, my marriage and my husband.  We are both Catholic.

      We now want to move to the Philippines permanently  so that he can be closer to his family again and be close to his father and mother who who are both ill with life threatening illnesses. His family was very successful in the Construction Industry in the Philippines and his grown siblings are all gainfully employed, one a physician.
 
      With that background, can anyone tell me if we have to acknowledge ourselves as a gay couple as we attempt to make our transition to the Philippines after the COVID crisis subsides there, hopefully toward that latter half of 2021.   ????

      We will already have made long term lease arrangements for him to operate  beachfront resort or for us to simple live there, on the beach if the economy will not support the resort and use the property as our home while he works elsewhere.   
   
     Can we simple apply as a married couple with all the legal paperwork from the US?  He also will have dual citizenship by the time we move next year in both the US and Philippines.  Do we have to define our marriage as a gay marriage or is there a review process that will mandate that we meet with a official, which will make the question a moot point.
 
      Do you know how other gay couples have handled this situation and what would you recommend is the best way for us to handle being together?   Any help would be appreciated.
