I want a romantic and sexual relationship with my best friend, lets call her B, (she's pansexual) but she has a serious bf, lets call him W, like they talk about getting engaged. (they are long distance I haven't met W yet) I am bisexual, demisexual, demiromantic, homoromatic. The demi stems from my PTSD and it takes me literally months to feel emotionally and generally comfortable with a female and be able to tolerate any physical contact; with males that takes years. B is the only person on this earth that I feel completely comfortable with and want physical contact with. however, B and W are a perfect pairing. But because it is so so hard for me to trust I am feeling very stuck in this situation. I am also realizing more and more that my trust issues are severe and directly related to my ptsd. which just really sucks
