Hugs. Make it a habit to cuddle before and aft sleep. Must say it out, cannot keep it inside. Of course try not to keep pestering and make him annoyed. Maybe you just do it and then slowly say it out, tell him you need hugs. Bear hugs, whatever cute hugs you cn name it. ♥️
Don’t bottle your feelings and have a heart to heart talk with him since we cannot read minds. Learn to manage your expectations too. He may be stressed too and is using his own ways to de-stress
