3. He will know you inside out
Say you laugh a lot, but one day you are upset about something; so he cracks a joke and you fake a smile, so as not to raise a concern. He will get to know for sure. If he really loves you, he will notice that you are faking that smile, and he will know that you are upset about something. And unless you tell him what you are upset about he will not leave your side because he feels responsible to make you feel better. He would not bother you, but he will let you know that he is here and you can share with him. It will surprise you that how much he knows about you without you talking about it.
