I told my husband in the spring of 2016 that if Trump won, I wanted out. We had a history of looking to find a way out of the country going back to the 90's when we actually went to New Zealand to take a look at moving there.
During the Bush years, we got involved with building a place in Panama. We both got through the process of successfully receiving permanent resident visas. Then Obama won and we gave up on Panama as it had gotten bogged down with issues and we no longer felt it was so important to have an out.
So, in 2016 I wasn't so sure we could take on moving to another country. I proposed we look at Hawaii. Blue state and as far away from the gun nuts and crazies as possible. Still the US.
After election night, I told my husband I was planning the go look at Hawaii trip for December. Did he agree that if we went he was prepared to move? He said no. So we didn't go look.
A year later we were separated and a year after that--2018--he killed himself.
Now I wonder whether I should be planning that look see trip to Hawaii for myself. Or somewhere else. Or whether I've aged (I'm 68) to the point it's nuts to think of such a move now.
I don't think your husband is nuts. There are now more guns than people in this country and a lot of people itching for a chance to use them.
