Being LGBT is so confusing because we dont have any of the nice relationship stuff handed down to us anymore, its all in the air. One would think being polite and some common sense might preclude one from asking out a roommate - but roommates to lovers is a thing that sometimes happens. Its all in the air, especially a freshly cracked trans girl just starting out. I bet there’s some crossed wires with specifically your roommate between platonic love and romantic love and the love we show the trans sisterhood in general, and hopefully she’ll get a handle on it as hormones settle (dont discount the horniness of second puberty and the power of a crush towards someone who is nice and frankly life saving to them, I get it as a nurse too)

We so often had to repress and feel ashamed about gender feelings along with however much dealing with romantic feelings as an egg was. Its easy when its been repressed for a couple decades at least for it to come out way strong.

You didnt do anything wrong, she shot her shot and hopefully didnt let the hinting phase get too awkward. Embarassing lesson, but ideally the both of you can come back from this and settle in to just roommates. If not, you or her might have to figure out alternate housing arrangements (especially if she cant let it go). Im surprised you feel used - I think you should interrogate that and think about it, you’ve extended help with gender stuff like HRT and fashion, youre roommates, and you seem to have done that on your own. Why feel used when she asked you out? Im sure she would’ve needed the help if she was straight and not interested in you. I can appreciate you feeling used when she touched you, hopefully you shut that down then or will going forwards with others - and hopefully she learns to start asking for consent, although I know it feels weird and unusual
