GF's dad is cheating. Shoult I tell her?

[cairo66]

I just caught my girlfriend’s dad cheating and I’m not so sure if I would pass this little information to her. I was running errands for my brother yesterday while he’s still out in some foreign dating tour and that’s when I saw my GF’s dad with someone else. I didn’t think of it as something at first, but then I saw them holding hands and kissing. How do I tell her that her dad is now dating someone of the same age as her? Do I even tell her? I’m so confused right now.

Yes. As much as it may hurt her you should tell her. Relationships are about honesty. She would feel worse if she came to find, you knew and didn't tell her.

I agree with A207, i would be very upset if a friend withheld knowledge such as this from me. friendship is based on trust and communication.

i would broach subject by saying i know something naughty about your dad, do you want to know what it is? i don't like to tattle but you are my friend.
