Should i try to patch up and try to reconcile our differences?

You don't say how long it has been. I would say give it a year or two. Send her a letter apologizing and if you dont hear back from her then just leave her alone. But wait til its been at least a year or more. Clingy people can be very traumitizing to others. It is scary when someone latches onto you and won't let you be your own person. So don't push it.
