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.
