Why does he answer iMessage texts but not my snaps?

His snap score is still going up and it has been a few days since he’s opened my snaps. When I text him through iMessage he still seems cool so I don't know what the deal is. He also mentions how he wants to hang out with me and stuff too. My question is why does he avoid my snaps or messages on snap?
