Guys, what do you guys think of guy friend sending you good morning and goodnight texts when he knows I'm in a relationship?

He only has few friends, including me, and we are all gaming buddies. But this dude sends me good morning and goodnight messages every day? Is it simply just boredom and platonic and nothing more? Or should I do something about it?
