help me

hey everyone, i'm going through a really tough breakup and could use some outside perspective. my ex and i were in a situationship, and almost a month ago he told me he didn't love me anymore and left me for someone else. he blocked me on everything right after. i've been doing no contact since then, but he's been the one breaking it. he's texted me a few times late at night (like 3am), asking about my dog and sending stickers, even though he's the one who said he never wanted to talk to me again. now i have an unread message sitting in my archived chats. i searched through every contact i have in my archives and nothing else came up, so it's almost certainly him. i've been too scared to open it for days. does it seem like he still has feelings, or do you think it's really him sitting in my archives trying to reach out again?
