it seems like you cannot accepted the fact that she had been screwed by someone else. ask yourself again whether you can accept the fact that your girlfriend is not a virgin?
if you cannot accept it, just move on, find another one, attend some religious event perhaps (i am pretty sure super religious girl are virgin until after marriage). if you continue the relationship like this, it will definitely not end well with you due to your insecurity.
IMO, a lot of girls has done it before with their ex, IMO quite normal unless she is a swinger and get screwed by different c**k every week.
