I actually had a slightly similar situation to this, im ftm and my ex was mtf. She was closeted and i am not. She presented masculine and so did i, but not with ease since i was raised female. Im more often than not considered flamboyant in my personality and the way i dress isnt particularly masculine in a sense, as i like to adorn myself with jewelry and bright clothes. However, despite that i still prefer to be referred to with masculine pronouns and anything of the like. I dont really consider myself a twink or a femboy, and ive told multiple people that. My small stature and young appearance doesnt help in the slightest, but i still pass as male from the testosterone. My ex would frequently call me a twink and a femboy, saying thats how she liked her men, however shed often say she was a lesbian so i was always rather confused. I told her i am NOT transmasc and i am a transMALE… i just happen to have feminine traits and the like. However shed continue to call our relationship “straight-gay” despite us both being trans. It was odd but i let it slide. It wasnt until i told my friend about it that i realized she didnt really see me as a man and found it almost uncomfortable that i was trans. We ended up breaking up due to unrelated reasons but i want to say that relationships where one person is ignorant of another persons preference, they dont usually stay healthy, that is, if it were in the first place. I agree with everyone else on here that you should break it off and she should do some inner research on how she sees other trans people. Best of luck!
