So have you decided what you want out of the relationship, are you staying or leaving? It will take a very long time. You and her will have to accept that your trust will never be the same but things can get better through time. It is still very fresh so you and her shouldn't rush through this difficult time. She should allow you to have doubts and allow you to continue to ask her questions when you feel uncomfortable. Communications will be huge and important. Have you thought about take a break at this time to deal with all the emotions on your own first and when you feel strong and ready maybe then you guys can come back together and talk things through? The trust will never be the same but because you guys love one another it can still be possible to stay with one another and to continuously work on the relationship. First decided if you and her still want to continue with the relationship, deal with your own emotions individually and when things are stable then you and her can then talk it through and come to an understanding of what has happened. The betrayal can rip out your heart and its imaginable that things can move forward but it is possible but it will take a very long time. Be true to yourself and decided what you want out of your future.
