Well, just wait till the divorce, or deathbed, either or now, since they are legally married now you cant do anything about it. I think the law on divorce is like 2 years of separation before a divorce can be granted. So maybe the 'honeymoon' will wear off by then.
I dont know that much about gay people divorcing, but I do know that these marriage can be shams for property and financial reasons. Actually many homosexuals practice something like open marriage, they will marry one person, but still have multiple partners on the side cos they cant get enough of sodomizing each other. And what happens is their prey gets younger and younger.
If someone isnt over to that mindset it might be they are just confused and think they are female, in that case they could have a sex change operation, but that costs big money. And it seems like most of them after a few years get complications and want to be changed back.
I know of people that turned 'gay' and left their husband or wife and even children behind to pursue their 'lover' . It is only what they carnally desire and never mind the trail of broken hearts they leave in their wake.
