Am I supposed to let go?

Mi cellphone's vibration wakes me up unexpectedly. I open my eyes and, in the darkness, I look for it on my night stand. I grab it and look at the time, it's only 11:14 pm, I think I fell asleep while doing my homework. The text is from Nick, wishing me sweet dreams, I left him talking to himself again. Mi fingers fly fast across the keyboard while I tell him that I fell asleep and I wish him sweet dreams as well.

"Don't worry beautiful, I know you were tired :) talk to you tomorrow, love you."

His texts always draw a smile on my face, but after a few seconds the happy feeling is replaced by guilt, when a second message pops on my phone's screen.

"I'm going to bed now, guess you fell asleep. Good night princess, I love you."

That's Sebastian, my boyfriend
