No. Never had sex, still a virgin. Of course, not necessarily the sort of virgin that would actually make a good wife unless she's completely changed her mindset. But still a virgin.
Yet at the same time - don't do any of that.
Could have a long discussion on that one as arguments can be made both ways. So the short answer is that it is down to her husband to prayerfully determine what is the right approach in that situation, taking into account love and forgiveness. He might have such a long complex discussion in the process of determining his answer, but I don't think we need to have it over a hypothetical. The hypothetical will be far less informative than the real.
If you have a real situation in mind that you need an actual answer on, we'll quickly find a lot more clarity. If you don't have a real situation in mind, this discussion will go round and round for 100 pages and nobody will be the wiser at the end. It's just how these things go.
