My ex boyfriend and I broke up 6 months ago. We were both thinking it but it was he who ended up initiating the break up. We’ve never contacted each other since then; no texts or calls. He did however look at my Instagram stories and liked a few IG posts but I think anything of it.. until he recently reacted with an emoji to my recent IG story. I know that’s not a huge difference from watching my stories but does that mean anything? Why would he do this?
