Hello House,a friend sent me this puzzle and I want to share it here. What do you think ?

A guy and his girlfriend went to commit
suicide on top of a 10 storey building
so dat God can officiate their
wedding in heaven. The plan was to
jump off d building at the same time at
the count of 3. So after the count the
guy jumped off but the girl didn't
jump. She looked back and said
"though love is blind am not blind".
She den walked away. As the guy got to
d air, he opened his parachute and
said " though am madly in love, but
not mad to die for love". The
question is who cheated between the
2 of them?
Pls be honest and objective with clear examples
