Relationship Ideas

Ok, so long story short. Me and my guy are high school sweet hearts. Been together since senior year (4 years). We started having problems a bit over a year ago. And it's gotten a better. We never fully on split up. We never moved away from each other. We never stopped sleeping in the same bed. We never stopped taking care of each other. We never stopped saying I love you everyday and meaning it. He is my best friend, and I want to spend the rest of my life with him. I don't know what to do. Should I hint at him to maybe pop the question? He already knows that's wht I want.
