If you suspect a woman cheated on you, how do you trick her into admitting it?

The woman I am with won't cheat on me.

Why don't you just ask?

If you're waiting for her to confess you're wasting your time.
Finding will hurt you even more.
Just tell her you know her interests are somewhere else and cut all contacts.

hey..if you were cheating on me and there were two versions of you and one tells the truth and another a lie, what would the answer be if i asked the other one of you what the other would say?.
They hate riddles..

You don't trick her...you just observe and wait, IF she's doing it she will eventually slip up and lay the evidence right in front of you (I know from personal experience).

Put purple dye in her vagina, then ask every guy you think she knows to show you his dick. Say it's for a research project and you work for the government!

Hmm well if I knew the guy she was doing it with I would set up a secret meeting and then pop up out of nowhere

More than 1 way but i would prepare to leave than the admitting process

I won't. I would just tell her how I feel and walk out.

They talk in their sleep

You don't. You either assume that it is true or you assume that you have decide that low self esteem and you overthink simple thing.
And if she did... what do you want to do about it? What will it change? Do you stay in your own uncertainty or do you allow the both of you to be happier alone?

Check her phone

Trick? what the fuck, you are not in school just ask
