We had an argument over a week ago where it was implied that we were broken up. I had even asked at the time if he wanted to break up and he said that we should have a face to face. Instead he's been sending platonic sounding text greetings every day and some small talk. I politely reply because I want to leave the door open to talk things over. Not sure we'll even bother with a face to face, it seems obvious that it's over. Last night he messaged me out of the blue, along with his usual good night message: "Random fact, when I was a kid, went to visit the northern coast of Peru, and I found a seahorse. I have been fascinated by them ever since." Any ideas on why he would write something like that? Weird.
So text your ex about it right before you go to bed?
