If you feel good doing so, talk to your father first and tell him how you feel. I think the way you described your bond with your stepmother in the beginning is a perfect description that you should definitely use while talking to your dad. Threaten him by saying that if he doesn't give up on the new girl, or cheating in general, that you will tell your stepmom about it. Also tell him he's a horrible person for doing that to everyone surrounding him0
Go talk to your dad about it. Either he will deny it, get annoyed that you figured it out or apologise to you and his girlfriend he was cheating on
If he doesn't apologise, threaten to tell his girlfriend (the one that he isn't cheating on).
If he STILL doesn't apologise go and tell his girlfriend.
I know it will be hard, but you have to do it. To keep you all happy.0
It's one of those weird ones as acting to fast would directly effect your life as u live with him and if u cause a problem for him can you ensure he won't throw you out?0
Go and warn your dads girlfriend, its the right thing to do, she doesn't deserve that, and you don't deserve that. Your dad is an asshole jerk imao.60
What Girls & Guys Said
Talk to your dad about it, it's unfair on you and particularly shitty that he's doing it while you're in the house. If he understands and puts an end to it then good, but if he carries on that's when you tell his girlfriend.2
Just straight up warn her.
With all due respect to your dad, he doesn't seem like a man with a conscience so it would be pointless to give him a warning. I am so sorry that you have to deal with this.0
If I was you... I would personally let your stepmom know but make it seem like it's an outsider telling her so no one knows it's you. Make a fake Facebook account, send her a message explaining everything he is doing and add in details so she understands it's someone who has to know him closely and is saying the truth.10
Oh no, not men, they have an innate protective instinct towards women
-_- warn your stepmom and move out with her.0
You’re in a pretty crappy situation, I would definitely warn her!0
Tell him you know, and blackmail him. Him being your dad doesn't excuse him from being a cheater! Either that, or secretly collect evidence. Play it at a family function. Destroy his reputation. THAT'S how to hit hard!13
I would warn her because of what the discriptipn sounds like, your dad would not react well.0
Talk to your father, and if he doesn't take you seriously or gets angry at you go to your stepmom and tell her everything.0
Stay out of it. he's an adult what's done in the dark will come to light eventually0
You shoul inform your step mom!.
That's the right thing to do i guess10
Just hint at it when talking with your dad.
Not all swingers do it in the same room.0
If I was me I would warn her. Personally I despise cheaters10
Family > Strangers. Why would you betray your father? How would you feel if you were cheating on your boyfriend and your dad sided with your boyfriend?11
Move out with your step mum0
You shouldn't really get involved.0
Low key I’d probably tell her to break up with him and take me with her 😬10
I think you should tell her.0
the right thing would be to warn her0
Don’t get involved.0
Warn her n run away with her if u can!20

I kind of read the poll wrong somehow, but I mean to choose to go warn your dad’s girlfriend. It’s for the better good and in the long run, she’ll surely thank you for that. Your bond with her will still be together, but it really hurts knowing that your s/o was cheating on you. You letting her know that will allow her to take the initiative when bringing it up with your dad. If she wasn’t planning on telling him, there’s a high chance your dad would act like it never happened, and she would going on thinking that he never cheated on her. It’s unfaithful. Go ahead and tell her. No offense, but what a asshole.
