I have reason to believe my father is cheating on my mother.

Tell your father first to cut that shit. If he doesn't, tell your mother.

You don't sound like you're 100% sure he is actually cheating. Talk to your Dad and ask him about it.

If he confesses, urge him to stop immediately.

Whatever you do, DO NOT tell your Mom. If she is going to find out about it, it HAS to come from your Dad. If he is cheating, and you really want your Mom to know about it, just tell your Dad he has to tell her or you will.

If you go behind his back and tell her about his infedility, their marriage will be over and your Dad will resent you. I'm guessing that isn't what you want.

I indeed do not know for sure but there are some clues lately.

The biggest i've found today.
He has a small wallet he usually only takes with him when he goes to his job and it had a condom in it.

Kinda weird that i know this but my parents don't use condoms as my mother has become infertile.

OP, there us nothing wrong with cheating. You shouldn't concern yourself with your father's personal business

This is going to be very hard for you to accept, but

THIS STORY IS NOT ABOUT YOU.

Keep out of it. Say and do nothing. Just brace yourself for the explosion when and if it comes.

>implying she should take part in the betrayal of her own mother

0/10, the betrayed party should always be told. Especially if it's your own parent, no matter whether it's your father or your mother being betrayed.
