An ominous text message sends me into a tailspin

My bf texted me this after a fight: "no matter what happens, I love you, don't let things sour our memory"

This scared me so much it triggered my abandonment issues again. I have never felt this in so long and it actually terrifies me. I had to tell him that I said some of the things I said last night during the fight because I want things to improve, not because it's a sign of giving up. He hasn't read our messages yet because he's asleep.

I'm so anxious right now and will be for another 6 hours until he wakes up.
