Weird behaviour?

A married man who flirted before and said he likes me/ finds me attractive got bk with his wife he said we can be friends but he still dms me every day while working never at home he still says occasional flirty thing he sent me photo of him with his kids few weeks ago and other day sent videos of his kids plus photo which has his wife in not him in it as far as I know his wife does not know he dms me or sends photos am I wrong in thinking he shouldn’t be still messaging someone he finds attractive he always initiates convos and my replies are normally short like ok or ye etc I really don’t get why he still dms me
