Is this the end of my marriage?

[P17]

A text from my W asking what the plan is for tomorrow with me and my D and what time do I want her over.

Very nervous about tomorrow. Especially if she tries to talk about the OM moving up or anything else to do with the R. Arwen_in_NJ suggested treating her just like a cousin when it comes to chit chat but not sure what to say if she brings R or OM stuff up - do I just tell her I don't want to discuss R issues or do I let her talk?

I did actually think she was going to cancel tomorrow as I really couldn't see the OM putting up with her coming out with us for the whole day (she will be away from 10am until 7pm with us and then off somewhere until 8.30pm) so she's caught me off hoof.

Anyway, advice appreciated on how to deal with R talk.
