You’re hurt and he’s the reason why you’re hurting. He tells you how hard his life has been. You want to tell him you were just there all along and he’s making you feel you are not enough. But you kept silent, because you know saying those things would only hurt him more and make him feel more inadequate than how he already feels with himself. 

Your tears would do the same trick this time, and he wouldn’t know you had trouble breathing as you managed to type that smiley.

In the end, an “I love you”. But behind it are the words, “I’d endure everything… just don’t leave me.”
