Posting here because I don't know what else to do.
I live with my parents. This evening my dad left his phone open on a hookup/dating site, so I saw it. Took a photo of the phone on the site including username, found out he met someone from the site last Friday, when he was supposedly Christmas shopping.
He and my mum have been married for 34 years, little to no romance these days but care about each other deeply, or so I thought.
To complicate things she is totally financially dependent on him, quit work almost 28 years ago and hasn't worked since, to raise my brother and me. She has always done everything at home, I guess I'm so appalled because she does so much for him, and also because last summer she nearly died of severe heart conditions so I can't believe he's willing to throw everything away after nearly losing her. My dad's profile online shows he is willing to meet women the same age as me, which I just can't get out of my head.
What do I do? Don't want to say anything to anyone until Christmas is over, but who do I speak to first? My current plan is to tell my older brother (27), and work it out together. Sorry for the length of the post but I was struggling mentally even before I found this out, and I just don't know what to do.
