I am still married. We are still close but different now; sleep separate and basically are split but we are still raising raigan together for time being. Not that she didn't know what was going on. It just that my gender dysphoria blew up where I was unable to suppress it at all and She's not into women.
As for my sexual orientation... Usually a questioned reserved for the people interested in me
love is my orientation just like anybody else.
To answer the actual question if a trans woman is only into woman she's a lesbian. If she loves men and woman she's bi, if she loved men she's straight. If she loves other gender variant people chances are she also loves men and woman she would be pan sexual. If they aren't sexual attracted to others they are asexual. All are possible..
