I texted my ex after 37 days of no contact?

Today a few minutes ago I asked my ex how he was doing and he said “I’m alright. I hope you’re doing well”. And then I said: “I am, thank you.” And with an emoji he answered: “Good😊”. What does that mean by a guy’s vision? It was him who dumped me 2 and a half months ago. He is really alright when he says “I’m alright” ? And that smiley emoji? He’s been stalking me during no contact time but he denied it when I asked him today. After we said good night to each other and didn’t say anything anymore, he took 6 minutes online to leave our conversation.
