The speaker is grieving someone who is gone, and the poem is built around one repeated wish: to have them back. The opening and closing lines both begin "Wishing you were here again," so the poem feels like it circles around the same ache without finding any way out.
What stands out is how honest the speaker is. They admit the other person lied to them and even hated them, and they knew it. Still, their love never wavered, and they say the person will never leave their heart. That contradiction is the emotional centre: it hurts, but the love stays. The wish for "that fight again" is especially telling, since even conflict is better than silence.
The line about not being able to hear certain words "twice" suggests something was said once and then lost. The mood is quiet, raw and wistful, with a simple style that makes the sadness feel direct and unguarded.
