Don't blame the new girl. ML is clearly leading both girls on. Is it too hard to send a single text in a week? Or say, "ya I met someone at the mixer" to the 2nd girl? I hate MLs like him. FL can do better.
You know what, give me the drama, her younger co-worker is cuter, wouldn't mind some spicy action to happen between him and fl, before the inevitably obvious ending happens anyway.
