bad pen pal 

You meet a girl on a date, but realize you're not quite ready to get in a relationship. She calls you messy but reluctantly gives you her phone number. She then calls you her best pen pal and you talk every day on the phone. You realize later that life is short and you want more than pen pals. You ask her things like do pen pals kiss and she asks if you want to go to Mexico with her. A few months later, you find yourself renting a house next door to her but not sure how to surprise her with it.

Girl: did your phone get hacked? pen pals don't ask about kissing
Guy: I've been thinking about kissing you, I've been a bad pen pal
