I originally viewed these actions as improvements in our relationship, but I now wonder if they are just attempts to appease me while she was at home, with an end goal of her going off and see the OM. Were they a smoke screen or genuine feelings? I know see my wife as a people-pleaser to a fault. She'll say whatever I or the OM want to hear, but I don't know what or if she means any of it.
It's hard to tell how authentic some WW's may be in these cases. Personally, I believe as long as she's wayward, it's cause for doubt. I think a lot of women enjoy the "friendship" the M provides for them. (In my own case, I couldn't stand to be in the same room with my H, and he was a very nice guy). Some WW's are so good at being manipulative, until the LBH is totally deceived or confused by their nice behavior.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
