If he doesn't look at you like your the most precious thing in the world or doesn't treat you like your worth a billion bucks then darling he's not the one
Make sure he's proud to show you off to the world and loves to tell everyone how much he loves you, make sure he knows how to be a gentlemen and holds the door for you and makes sure you get home okay
If he doesn't look you in your eyes from time to time to tell you how much he loves you or makes no effort to express that love then honey walk away from that man
Know your worth and even add some change to it. Your amazing, make sure the guy you give your heart to knows that.
The greatest love; You either know when you have it or eventually figure it out when it's gone.
