Seriously he has literally helped me in more ways than I could even begin to remember; And would do anything, for anyone. But you see. He's dating a bitch. She is very obviously severly OCD ADD and Bi-polar. But she REFUSES to seek treatment. They have been dating for two years and she has a daughter, (not my friends) that my friend loves more than life itself. But his girlfriend, whom we shall call. Dirtycumslut. :) well. Rico suave puts up with this abuse. And her calling him worthless and her even cheating on him because he loves her baby so much. And no matter how much I try to tell him its not his issue. And he needs out. He can't bring himself to do it. This girl cheats, beats, and uses him. And she is extremely disrespectful to his saint parents. She's a dirtycumslut. But wait!!! The juiciest of all! I am a baker at Panera bread. She is training to become a baker as well.... I am her trainer.... I see her five nights a week. 8 hours a night. Knowing how she treats him. And she thinks her and I are best friends... What do I do?! I can't let her treat Rico suave this way. But dirtycumslut is my trainee. I have to be professional. Help me reddit.
