Breaking up is tough, but it’s better than staying in an uncomfortable romance with an insensitive guy. You want out, so let him know. In person or on the phone, say, "We’ve had fun, but this isn’t working. Let’s go back to being friends, OK?" Once you’ve let him go, don't second-guess your actions. Instead, have faith that your next kiss, whenever that might be, will have more sparkle. And it will be a first kiss with someone new.
