Jo,
I'm with mattsmom regarding the birth control. If difficult child is bent on being sexually active/promiscuous, there is not much you can do since she's pretty much old enough to make her own choices.
I imagine, were I in your shoes, I would reiterate the birth control conversation, as well as condoms for the sexually transmitted stuff.
Perhaps seeing where going now where fast will get her while spending time with her dad will open her eyes. Or, it could backfire and she will end up wanting the nothing life.
Any way that you could tell her once graduation happens she'll have to get a job so she can contribute to the household?
Hugs,
Sharon
