You'd do anything for him.
You watch as he gazes at her, admiration filling his eyes. You wish that admiration was for you. Why doesn't he see that you're so much better? She doesn't complete him like you would. She doesn't know him like you do.
You've tried everything to break them up. But somehow, they survive it all.
You watch in pure agony as he leans in to press a soft kiss to her lips, his hand sliding round her waist. They haven't even noticed you standing here for the past 20 minutes, that's how in love they are.
As he pulls away, they mutter and inside joke you know you'll never understand. It pains you inside and makes your eyes stung with tears... the fact that you'll never be in her position.
You stand there, holding back your tears, and the familiar choking sensation in your throat.
