No. No, no, no, no, no.
Speaking as someone who just came out of a relationship that ended due to circumstances similar to what you describe, let me advise you to run far, far away. I know it can be hard to just let it go and move on, but trust me--you're going to end up getting hurt, bad.
If she's done it once, especially this callously, she'll do it again. You'll never be able to trust her, and therefore any relationship there is doomed. Just move on before it gets worse
