I hope for the sake of your own sanity you decide not to dig deeper into your daughters recent comments.
I am guessing she never brought this subject up before and just blurted it out recently. If true statements, what she blurted out may possibly just be the tip of an iceberg.
If questioned, she might tell you more - much more. More than you bargained for. Digging around even online may lead to a huge world of hurt.
I would think very carefully before trying to find out more. This type of thing may be best left in God's hands.
Im sorry Amy that you had to hear these words from your daughter.
