Hi brokenhearted33,
I do agree that no contact would be helpful, why is she taking you shopping just as friends a week after she broke up with you? Whether you go with her is up to you, but if she is serious about being just friends, you may be setting yourself up for further disappointment by getting your hopes up.
I would not be cold towards her, as far as being rude or anything like that. I would act like you are ok with the breakup and that everything is going great in your life. Go out with your friends, enjoy yourself.
Getting her back will not be an instant process, don't pressure her or even act interested in getting back together. Be friendly and confident when you see her.
Regards,
Frank
