Help

Crazy morning, I sit down for my break and open my phone and see a notification that a person I'll call Fuckboy wants to be my friend on Snapchat. MASSIVE BACKSTORY this man dated both my best friend and myself back to back and some more complicated stuff in college. Then years later after the friendship breakup with her, he and I reconnected and were friends with benefits for a couple years. Then he randomly ghosted me no word like 10 years ago. A few years ago, I looked him up on Facebook out of curiosity and saw he was married now and had 4 kids and some quick math told me the wife was definitely pregnant already the last time he fucked me, hence the ghosting instead of telling me he was dating someone and knocked her up and was getting married. AND NOW HE WANTS TO BE SNAPCHAT FRIENDS AT AGE 40? HELP. Brookie Brat I need you both to read and comment plz
