Seriously Turtle, my H always wants to know, and doesn't seem like it is a big deal. I don't ask him about his life, why should he feel the need to ask about mine? I don't get that either.
That would be the reason no one knows of my date on Saturday afternoon except my dental hygienist (long story).
I think, to an extent, our Hs feel a lot of guilt. If they could see we "moved on" it would solidify their thinking in that they were right to go and OW is okay, because now we have someone too.
