The question

Can I assume jail time if my soon to be ex wife of 6 years, currently 27yo, brings to light that we had sex when she was 16? We're looking at separation and she reminded me of it. She doesn't hate me, just feels like she got married to young and she claims we'll be friends. She wants the chance to do things on her own. BUT she was grossed out that there may be proof that her mother has. A journel she kept in her teens. Maybe some pics. Doubt my wife will say anything to anyone ever (she even asked to not bother will lawyer/divorce lawyer) but what if mom did, after all this time.
