Never Trust Any one

Never Trust Anyone.

A couple decides to commit suicide after going through a really hard tough time in life.

So they both decided to jump off a 20 storey building to death.

When they got to the topmost floor, they both agreed to count 1-3 and jump.

On the 3rd count, the woman jumped but the man stayed.

As the man watched the woman fall, he saw the woman pulling out a parachute to land safely.

Question: Who betrayed who?

The man or the woman?

Justify your answer.
