Men Don't Call Back Because They Have Trouble Being Honest
If you and a man hit it off, trade numbers, talk for a while or trade emails, but he never seems to make the initiative to actually see you—then something else is going on. Men often have a hard time sharing the truth about their feelings with women they've just met. Maybe he's already seeing someone else.
Dating advice: Ask in a playful way, "I'm curious since you're kinda cute—are you dating anyone interesting right now?" Invite honesty from men and you'll get it. If you wait and wonder, you'll end up wasting your own time and energy.
