Is this the same girl you posted about here?:

If so (I'm guessing it is since you said you were with her a year) you aren't doing yourself any favors by humoring her and being her 'friend'.
She's over you. You're not over her. Proximity to her, and staying in touch is like rubbing salt in a wound. You need some distance.
Details in your other thread, coupled with the ones here also make me think she's got another guy, as well. Hey breakup excuse was really quite lame. You state in this thread that she lost her father recently, but the other thread says you broke up 6 months ago... I'm sorry, but the truth is a hard-hitting death brings most people closer to the one they're with (for support, etc), and 6 months is plenty of time to figure out whether you want to be with someone or not.
