I can relate to this. I also work with the girl who dumped me. Gave her everything bro. Attention, time, effort materials even good sex. I thought she is the one. I was ready to help raise her son. She even said that i made her relly happy. Then just like that she walked away too. I still can't believe that after everything, it was just easy for her to walk away. And now it's tough to move on. I work with her and i see her every fucking day and it's like we don't know each other anymore. And to add salt to the wound she would breadcrumb me. She would reach out to me and then ignore me. I'm going indefinite NC but she does this everytime and i feel like I ave to reset over and over again. Damn, how i wish i could transfer jobs but i can't. Guess I'll just have to man up then.
