Again, I hate to be negative, but it sounds like cake to me. Going out with bad people, making bad decisions, kissing someone. Or maybe she's still in the exploring stages with the good male friend you mentioned a few days ago, waiting to see how that pans out.
You said you aren't watching the kids, but wasn't it her friends that she was dumping them on..? Sorry maybe I am confusing your sitch with someone else.
I don't know the laws in Ohio but in Texas, unless the divorce has been filed in court and a temporary restraining order has been filed, then everything is still community debt/property. Even if credit is opened and used in just one name. I've seen it happen to a friend, sadly.
