Likes your posts but doesn't reply to message?

So, I met this guy online two days ago and we really vibed with each other , he also sent me flirty emojis and I really like him. he was liking and viewing my posts but yesterday he didn't reply to my message but viewed and liked my posts. Is it normal and does this mean he liked me but now he's bored?
