I am also going through the same thing. I’m not currently in a relationship but when I was in a relationship with my boyfriend I never questioned my sexuality. I feel the same as you when you said that this post feels like it’s your own words and it’s the only thing that has made you feel okay. I’ve been having these thoughts for about a week now. I have started going to therapy, but it’s only been a couple days. I’m afraid I can’t offer you any advice, but I’d love to talk to you more if you’re open to it!
