Not for me, if I suspect she is cheating on me id confront her and break it off.
If she wants to snoop trough my phone or computer or follow me around she is more then welcome to.. I have nothing to hide .

Im pretty sure alot of the votes are troll's like you have in any other poll.
But that being said if it actually is 20% I am still not worried seeing im a 100% sure mine wont cheat on me as she had an ex that did it to her and she knows the feeling it gives.
That is not something you want to do to your partner.
