My girlfriend has been on me for a few months to tell my mom that I'm pan/genderfluid... We've gone over a few times to tell her but i always chicken out. How do i start that conversation? What should i expect? I know she will probly be cool with it. I just feel once i tell her it will be final. My GF doesn't understand why i haven't and says that it is easy and i just need to tell her.

She has told her side of the family to help her come to terms with it but that kind of cheesed my biscuit and i know she only wants me to come out and be happy. I know once i tell my mom, I'll be coming out to everyone else but it just feels like such a huge step for me but to her its just something so small. I have a tattoo on my wrist branding me what i am which i make no attempt at hiding. I've had for 6 weeks and thought that would be the push i needed but im still freezing up. Help me please
