Trans-attraction can break up a marriage, but that doesn't have to be a bad thing.
Desires are good not "addictions". Attraction is good. It is not an "addiction". Love is good too and it is not restricted to just one person.
The way out of bad relationships isn't looking for better ones. It's changing your story about relationships.
Your love of transgender people is wholesome. Being trans attracted is good.
The way to that begins with the stories you're telling.
