So I don't know how to feel about this... My boyfriend of 8 months is out right now at Bakers having dinner with his female coworker Robin. I don't want to say I don't like her but I don't really like her since she made a rude comment the first time my boyfriend and I had a double date with her and her husband... Should I be upset?
