The forces are equal. The responses to the forces are unequal.

So why do you fall faster on earth than you would on the moon or mars? Do they themselves accelerate at 6m/s towards you?

You fall faster on Earth because the force is 6 times more than on the Moon. They don't accelerate at 6 m/s^(2), because even thought they feel the same force you do, they are many billion of times more massive.

Acceleration = Force / Mass

On Earth, your acceleration is 9.81 m/s^(2). Earth's acceleration toward you is 8.21 x 10^(-23) m/s^(2).

So the forces are not equal then

The force of the MOON on you is not equal to the force of the EARTH on you, that much is true. But the force of the moon on you is equal to the force of you on the moon. For any two bodies X and Y, the gravitation force of X on Y is equal to the force of Y on X.
