I am not an expert, and definitely one who has asked my women friends(female perspective)on scenarios I have been involved with..I just posted one under "I Over Did It"

But from an outside perspective on your situation is this...Its sounds complicated LOL I mean you dated for 6 months and she was over your house for a face to face break up and clung to you for hours...She does have feelings for you obviously, but she might not have that heart pounding LOVE for you...I would just take a step back..slow down..do not sever ties with her but don't be like it was before...she might realize then after a few weeks that your the best thing for her..I wish you luck.
