Doubles never lie

Tittyfuck her

Don't do it. Her cheating is the only thing keeping the marriage together.

Leave it. Things aren't black and white. You don't know fuck about their relationship and it is not your business.
Don't be a damn incel about this.

Get proof, give that proof to your father, this will prevent her from taking alimony in the divorce. Then insist to live with him. Teach her that infidelity effects everyone.

This is your only option

Stop being such a fucking roastie, there's no justification for cheating on either side.
E d the relationship if you don't want to be with that person anymore.

why get married if you don't believe it has any meaning?

Is your mom employed?

Nothing is that simple.

Because marriage is a contract that bind two people into a single legal entity for better or worse. Adultery is an action that compromises that contract.

Not him, but in fact, it's that fucking simple
Honestly the only reason this things happen is because they refuse to really know eachother enough to trust their problems, and thats exactly why people used to marry before, to share their lifes, if you cheat, you are betraying the trust of your partner, it doesn't matter who did it

Explain how cheating, which implies one party betraying another to fuck a third party, isn't simply a betrayal?

This has nothing to do with something like an open relationship. Cheating has it all there in the title where someone is doing something outside of the agreed upon rules.
