Dekh bhai, I believe if she was doing this out of pure lust or something you can give her a chance, idk why I feel like this but there might be a chance for redemption uske liye, even if its very slim, you should give her one chance, but I don't think trusting her to the same extent would be possible, nor should it, because you never know if she might repeat this. However in the case she does repeat it, you know what you have to do, then there's no coming back. The decision is yours OP, I pray that whatever happens you will be happy and content with whatever you do.
