Just play it cool throughout the next week. Everything, no matter what (obviously disrespect and boundary issues excluded as they always are) is just fine with you.
Throw yourself into your kids. Mine have been a very healthy escape/distraction from the sitch at times. AND, a woman LOVES to see her husband playing and having fun with her kids. She may not say anything about it (mine hasn't), and that's ok b/c you aren't doing it for her. You are doing it for you. The love I have received from my S9 and D5 has been a God send at times, and my kids have no idea of what they are doing. They just love me unconditionally, like I want my W to do. Take that where you can get it for now. It will get you through.
Just enjoy the moments to come next week and make things easy for your W (I don't mean kiss her a$$). Give her space and do what you can to take the pressure of the sitch (she's in it too) off of her. Let her own her issues, but don't be a source of pressure to her. You might be surprised at what she does.
