I’ve started ghosting people, and I hate doing it. I prefer to be upfront about my lack of interest — a quick “Hey, it’s nothing personal but I’m not interested” works for me. I don’t state why I’m not interested; simply that I’m not. Unfortunately, I’ve still had guys curse me out and call me awful names when I send brief messages like that.
I’ve also dealt with messages like “Oh, you think you’re too good for me?” or “You need to give me a chance. There’s no way you aren’t interested. I’m a catch. You’re just playing hard to get.”
That’s why ghosting works best.
