My wife is going out for the evening so I am going to follow her around.
Why are you planning on doing that? Is she expecting you to follow her?
She deserves it. She has been unfaithful.
You shouldn't assume that your wife is being unfaithful to you, and it is wrong of you to follow her around trying to catch her. You should trust your wife, and if you think that she is getting bored, try to respark your relationship.
I know that I'm right I know it... The punishment must be severe and my paranoia will know when she's cheating.
You don't know that she is cheating, you need to not accuse her unless you know for certain. You could end up ruining your relationship with her.
