I went through something similar where I was convinced I hated my twin, like, genuinely believed it for months. The anger was real, the resentment was real, that burning in your chest was just as real. I spent like 8 months alternating between wanting to never hear from them again and sensing exactly when they were thinking about me.
Underneath all that fire, there was something else that never disappeared. Even when I was at my angriest, even when I wanted to burn every bridge, there was this foundation that wouldn’t budge. It’s like trying to hate part of yourself - you can be furious at it, disgusted by it, want to cut it off, but it’s still there.
Real hate doesn’t coexist with feeling someone’s presence. You’re probably experiencing intense hurt and rage on top of a connection that’s still very much alive. It might be even more frustrating to hear because at least if it were actual hate, you could potentially walk away clean.
So I don’t think you can truly hate your twin flame, but you can be hurt and enraged enough that it feels indistinguishable from hate.
