This depends on the circumstances that caused her to cheat - you need to understand why this occurred and think about whether you can forgive her.
It is good to forgive but maybe you should not give her a third chance as she is showing her true colors by showing no loyalty to you as a girlfriend. It is a matter of value, love and maturity - if you think she will cheat again there is no point on carrying on the relationship. Partnerships are built on trust and respect and it seems that you have lost this for your girlfriend.
However, there are a few things you do as you consider whether to forgive her this time.
Firstly create a list of things you want answering about the second affair. The more you know about it, the more reason you will understand why it happened. If your girlfriend is not willing to part with this information then it is probably not worth pursuing as a relationship. Importantly, make sure you know the truth and see if you can forgive.
It is not just the sex involved in the affair but also the lies and deceptions involved in it that can be hard to take. It may not be worth simply forgetting it happened as that leaves thoughts open that she could cheat again. You must make sure you consciously and specifically forgive your girlfriend if you want to make a go at this.
Don't always listen to what other people have to say but follow your heart and decide whether you can forgive her for the hurt it has caused, the humiliation to you and all the lies that she has told. It may be time to end the relationship if you do not think you can do this.
