Status Updates From Bad Habit (Bad Love, #1)

Having a hard time reading this one, I am most interested in the plot of why he left than anything else. The whole prologue and how she was 14 when they their first sexual encounter - sooo icky. She is now 17 and comments of how much she has grown and developed as a woman - almost throwing up here. Then the sex without a condom even though he is a manwhore? YUCKKKKKKKK
