You know he is yours, just yours. But..the way he laughs with her and not you, makes you envious. The way he talks to her and not you, makes you envious. The way she catches his eyes in the crowd, you know you cant. The way....... He cares about you, he doesnt for her. The way he loves you, he doesny love her. The way he misses you, he doesnt miss her. The way he looks for you to arrive and divides a bigger piece of attention towards you, he doesnt give that much attention to her. The way he would smile and feels when talking to you, he doesnt feel the same for her. So...trust him. Be honest to him and remember he is yours. Tell him whatever you feel without the fear of what he would think about you. And know that even he is loyal to you. Remember you love each other.
