What will you do to your cheating/shrew ex gf?

Guest

Been going out with this gal who actually had a bf...but they broke off and she confine in me...saying she love me. We start going out very often and slowing I falled for her...hoping she isn't taking me as a rebound.

Six months passed...like normal couples, we have arguments but not to the extend of not talking to each other for weeks...but came one final day that she wanted to leave for the reason that she's tired of it already but from her actions I find that she's looking for an excuse to move on to another guy which I so happened to know through a close friend where she's working...

I had put in a lot of effort in this relationship...what should I do? I feel like getting back...cause she almost infected me with some STD...but tested negative...but the trauma is too much for me...should I expose her doings and actions to the guy she is seeing now as he might the next victim or inform her parents about her behaviour? Because after speaking to a doctor friend of mine, he deduced that she might be suffering from emotional problems...

Pls help...
