That's a very interesting scenario. I think it is very difficult to come to a determine whether you have influenced her view of her own identity through transitioning with what you said. While many trans people hate identifying with activities or qualities of their birth sex, this can also equally be applied to many cisgendered people as well. For example, I know straight men who are more girly in a stereotypical sense than some trans women. The real factor comes down to how one feels internally and how long those feelings have persisted. Did your gf have consistent feelings throughout life that she is a man or would have been happier living as one? Or did these feelings appear after she discovered your identity? It seems most of us have had these feelings for most of our lives. Of course, she could have realized things latter in life, but it would be questionable if she didn't have any sense of her identity before your transition. However, gender identity can be really complex and is not simple for everyone to figure out.
Clearly, you have some knowledge with this and would be able to help find her true feelings. I think you should talk to her about your concerns and learn more about her feelings. Additionally, maybe you guys could go to a support group or therapy together.
P.S. You must be an awesome gf to support her through this time. I say this as a straight woman,lol.
