Who's the bigger betrayer

Your mom, who recorded it all.

It's good that neither committed suicide, but both of them are wrong if this was an attempt to kill the other one and pass it off as a suicide.
Both need counseling and probably a divorce.

The wife because she came prepared with the parachute. The husband was ultimately too afraid to jump off the building.

Wouldn't he notice her parachute?

Well the guy didn't jump because obviously he looked over and saw that she was wearing a gigantic parachute.

Maybe she didn't trust him to jump so that was what the chute was for, but had he jumped she wouldn't have popped the chute. He betrayed her so she had to use plan B.

wife. the husband obviously noticed the parachute. i mean dude, how do you miss that?

The husband. The wife probably thought he wouldn't jump so in case he didn't, she had a parachute for precaution. When she saw he didn't jump, she was able to release the Shute.

Both....obviously their love wasnt enough to keep each other happy enough to live

Husband... If he'd jump with her maybe the wife wouldn't have opened the parachute... Maybe...

It's the wife you wing nuts! She wouldn't popped the parachute even if he did jump, basically tricking him Into dying alone.

Plot twist: they didn't intend to kill themselves, just jump off a building with parachutes, and the husband chickened out because doing that is illegal and he didn't want to go to jail.

Like really...how would you not notice a parachute?

It would be pretty hard to hide a parachute. And why would you wear a backpack to your suicide? Logically the husband must have known she had a parachute.

Husband! Because he didn't even jump
