At least she is talking about R a little and taking blame for her actions?
It's good you guys are talking, I wish my W would open up but we're not there yet. Just my opinion, but don't let your guard down because she seems to be sorry. Maybe getting the vibe from you that you won't put up with it anymore. Be respectful and firm but be sure her actions match her words.
Sounds like you're in a good place right now. Keep up the good work!
