Is flirting cheating?

3rd. You can absolutely be nice and friendly without giving off a flirty energy. I wouldn't say the act of flirting itself is cheating, but more so the intentions (like nervousjuice pointed out) mean with the flirting. Exactly WHY are you flirting and what are you trying to gain out of it.

If any answer would make you feel uneasy if done from your own partner, then yeah, it's probably not the move.
