I completely agree with Cutter about it all. In my sitch, my MIL did not reach out to me about the affair; she reached out about her grandson. She was very embarrassed about her son's treatment of us (she told me later) and didn't know what to say.
I think your MIL possibly didn't know what to do in regard to contacting you about your mum. She is possibly trying to stay connected with you and your D separate from your WAW. That is what my inlaws are doing and it's okay with me! Again, I am not angry with them for something their son is doing!
Just sign cards w/ your name and D. Not the right time to be manipulative. I like how Cutter is consistently mentioning the same 2 names of women to people so that it can get around that he could be dating! It just seems more believable and classy--not a game! (even though it kind of is!)
