Hey, not sure if I exactly have an answer for you, but can relate to feeling erased. I remember a few years ago, I'd broken up with a boyfriend and gotten really close to his roommate's girlfriend (LOL). She was so gorgeous and looked kind of like Aubrey Plaza who is my ideal gay crush. But also we just got along really well. I tried expressing to a few friends WHO IDENTIFIED AS BI that I felt like I was into her romantically/sexually, and they wrote me off with, "no, you like guys too much to be gay," and "oh I think girls just like other girls." Anyway joke's on them because we ended up having a hot makeout session a few months later. But I've had this re-occurring theme of hooking up with other bi girls who get into serious straight relationships soon after and it leaves me feeling kind of rejected and dismissed, like was that even a thing?

Also, just small comments over the years about how I should put more effort into how I dress, ie. dress more feminine (I LOVE clothes, my style is just kind of grungy, mostly jeans and baggy shirts or sweaters, but put together well thank you very much). Or how I should wear more makeup, do my nails, etc.etc.

I dunno, it sucks. I'm lucky to live in a big city with a huge LGBT+ scene, so I'm not dealing with the awful discrimination some people have described, most people are pretty open. But I do deal with feelings of unworthiness and feeling out of place, and I wonder if it could relate to this.
