I'm trans, and even tho she ain't supportive, she's respectful about it. However.... she has recently taken to using the fact I'm ftm against me

Literally just now, we had to carry some groceries from the store out to the car and they were a bit heavy so I asked her to carry the milk. This transphobe looked me dead in the eyes and said "I thought you were a big strong man." Now obviously I know that not all men have to be the big strong stereotype... but you bet your sweet ass I carried all those damn groceries to the car and I'm about to carry them all inside
