Is it just me or is it really weird that my friend constantly hangs out with her ex boyfriend's two best friends? She and her ex are not really speaking (they've only exchanged 2 or 3 friendly, "how have you been?" emails since their breakup in July).

She claims that she likes them a lot and wants to be able to hang out with them regardless of whether or not she and are ex are together. BUT she also occasionally mentions that she wonders about her ex and really wants him to want her again.

Does this sound like she's wanting to hold on to pieces of her ex by staying friends with HIS friends?
