Ive gotten the "Listen, I know you didnt want to get serious but we can't keep doing this forever. Where do you see this going?"
The truth set me free
I've gotten that once from a couple of girls I had sprung for a minute. They had become friends somehow. One girl I was a bit more discreet and didn't really talk about me the way the other did. Way more emotional though and got mad at me more often, especially when they became friends.
The less emotional one, I don't know why, I hit with the "those other girls are my friends but you're more than that". The discreet one though I basically told that it's never gonna happen. Don't know why I did that either cause she was one of the best people I've ever met and had the pleasure to make moan.
