Coming out and never doing anything about it cuz life

So I am born a male but I’m trans I’m 100% a girl in a dudes body. there’s nothing I can do I have a gf I love her so much. but if I transition she’ll leave me and she’s the love of my life but it also looks like transitionings not a good idea cuz who the world views the idea. If I were to I’d probably never pass because I’m getting on the older side of (26). So I’m most likely gonna have to live with my male bod tho I wish we can speed up the future so I can fully change into a girl and feel comfortable with who I am. But there’s my pice sorry for grammar spelling and stuff I don’t care if it sucks

Edit: did this ever blow up thanks for all the comments good and bad I wanted both to see both side and I sure did I do think I’m gonna keep going. for people asking how I feel like a girl in a dude body is well I side more with women and I don’t fit in well with guys and dudes are attractive. I also forgot to mention I understand if my gf leaves I’ve mentioned it to her before and she told me and I completely get it I do but this would be something for me. Once again tho thank you for all your comments they were really helpful and got me thinking.
