coming out as transmasc to my possibly lesbian girlfriend

Hi, I'm a closeted transgender man, but recently i decided that it's about time to come out since i'm turning 18 in april and would like to start hrt as soon as possible. I came out to my girlfriend 2 weeks ago and nobody else at the moment, but i don't really know how to feel with the things she said to me recently. She is not really sure whether she is a lesbian or a bisexual so me being a man is kinda troubling for her. Yesterday she said to me that since she is too afraid that she will accidently out me to my friends by using the right pronouns she will just return to using she/her on me and my birthname even when we re alone bc thats too confusing for her. Later on she apologized and explained that she said that only because shes rlly stressed about the possibiliry of being no longer into me when i transition. Then she said that she wants me to come out as fast as possible to our mutual friends so that she can test out whether she will still be into me when i start "being a man" officially. I don't know tho if i'm the asshole and being too hard on her while she is just being overwhelmed by everything thats happening rn?? I rlly don't know what to do now
