Search Results: ex wants to work things out

Last year I transferred to a different store for work. A girl in another department was immediately super interested in me. But I didn't ask her out because of risk of sexual harassment and I didn't want to shit where I eat.
She eventually asked me out, and I agreed, as I didn't think much would happen. We went to her place, and I thought we were gonna hookup, but she introduced me to her parents. The date was awkward and she said she would do it again. I asked her twice I'd we could, and she would ghost me so I gave up.
Things got serious with a girl I really liked and we got in a relationship. But my coworker kept playing games and I was annoyed so I started avoiding her. I soon found out she ghosted me cause she was hooking up with her ex. But more power to her.

I've been trying to avoid her and talk to her cause she just wants to play games and not be professional. Today I was talking to a coworker about lunch and she jumped in saying she wanted some, and was sarcastic and wondered why I didn't offer her any. She said I could have texted her, and I said why, you don't answer anyway. She said she would about work, and I laughed and walked off. She made a comment about how I don't offer her food and stuff, so I said I did once and she just said no. And she said I could have asked. And I said, why? You don't text me either. Then she said I was trying to make her seem like a bad person. I just shook my head and walked off before I started shit I'd regret.

I'm regretting putting myself in the position to have this conversation. She likes to force herself in the conversation and she just constantly pisses me off. She's incredibly nosy and asks about my girlfriend all the time and I just wish she'd leave it be. Exactly the situation I was trying to avoid.
