<human>: Was dumped 20 years ago. Ex GF of 4 years moved in with new BF the day she moved out of our place. 10 months later some mutual friends invited me out for lunch.  No one told me my Ex would be waiting at the cafe holding a 2 month old baby.  She told me they just had a wedding and that her husband doesn't care about the paternity. She told me her husband will be the father no matter what.  She also told me she knew I had gotten married and she knew my wife was expecting soon.  She wanted to be the one to let me know what might be mine and she wanted me to walk away.

I don't have a facebook account and never have, but a friend asked if I could check out their PC. After clearing temps and rebooting I click on Chrome and facebook is the default webpage with the name and password saved. My curiosity got the better of me and I searched my ex's name. Now I'm back in that dark uneasy place.  I've spent the last 3 hours looking at the child now college student's facebook page. I wish her photos and selfies were conclusive either way, but I honestly can't tell if I am the biological father. Time to wipe the search history. Time to stomach the whirlwind of emotions. Time to walk away again.

Condense the text into a few key points
<bot>: Walking away from paternity to spare 2 homes. / I know my curiosity is not enough, but would there ever be a strong enough reason to justify finding out?
