Most Helpful Girl
It doesn't have to be etched in stone here, dear, the writing is on the wall That... She says it is possible her past relationship might have a little bit to do with it...
She has been this Honest Jenny Jon with you on her own end so she doesn't start something she knows she may not be able to finish. She isn't over the Other just yet, knows you could end up a Rebound Robert, constantly comparing him to you and knows... it could go down a badly beaten path and War of the Roses.
I feel she doesn't know you well enough to really judge anything but my heart and my wise ol mind is telling me Truthfully she got cold duck feet in going too fast into a Relationship with someone else and she cannot handle it right now.
Be friends with her, if anything. If you want to stay in the running, feel she is worth it then start off slow with the flow. Just don't wear your poor heart on your sleeve in case one day... she should just leave.
Life is a gamble so it's up to you if you want to take the chance into a potential but maybe possible.. Romance.
Good luck. xx
