Gently, and rhetorically:
She has been involved with this guy (who talks very sexually) for six months. Why do you believe they have only kissed?
The shame of being unfaithful, especially given your relationship to families here,
could be the cause of the tears - could it not?
I agree with the others, if there was SA in her past - she needs to deal with that, before any decisions are made.
I wish you peace, even just a moment of it - cause this stuff is just so hard to sort through. Be sure to get enough fluids, force yourself to each something, anything, just a smoothie if that is all you can stomach. ((innocence))
