Healthy communication

Hello friends

So I’ve recently figured out my sexuality! I now identify as a bisexual lady. I have yet to tell my boyfriend of one year. He is the most understand, loving angel who gives me the world and more! However, I am terrified to tell him. I’ve only ever been in toxic relationships before I met him so that may be why I’m freaking out. I fear that if I tell him about my new self discovery, he’ll question our relationship or freak out. Do I have anything to show that he’d do this? Nope. He is basically the perfect boyfriend. My mind is just fighting against me. Does anyone have any advice on how to go about this? I want to tell him because I love sharing everything with him, especially if it’s something important like my self-identity.

Thank you my lovelies for the help
