When I was dating, I kept a fake phone number for guys who were jerks. Its voicemail said, “If a girl gave this number to you, she’s not interested.” I never actually gave it out, since I usually gave most men a chance. Still, I wished for a better way to protect my privacy. Giving someone your number can feel like a small decision, but unwanted calls can quickly become uncomfortable. A little protection makes dating feel more relaxed.
