I'm going to turn down someone I intentionally led on.
How did you intentionally lead them on?
He and I aren't that emotionally close and it was fun flirting with him for a while, but the dry spell made the situation awkward
You should not be leading anyone on. It is good that you stopped it and are letting him know where you stand.
I was having fun, but not its time to end.
Next time, try not to lead someone on. It is disingenuous on your part to do that. How would you feel if someone had led you on?
