So the W stays out all night (at other mans) and comes home at 9am the next day. Says good morning to the kids and then comes and sits on the sofa with me. All happy and asking me how the night was with the kids. Then saying my traininers that i was wearing are all the fashion now and some other conversation.

Im thinking its wierd behavior because she knows that i know where she goes. Am i correct in thinking this?
If i was sane i would feel guilty and try and avoid the other spouse.

This is the 2nd week in the row she has done this and acted the same way.

All part and parcel of MLC?
