they enjoyed every minute of hurting you
This is what we think.
"the reality is that they weren't thinking of you at all"
I forget where I got that from, one of the books or the second MC.
That is what our realities are when the affair is going on, they usually simply don't care about us. I could see this in retrospect. My wife acted like I wasn't even there, except to avoid my intrusions into her life.
Which REALLY hurt.
One memory sticks with me; I arrive home from a long day at work, empty house, except for the dogs. I am tired and hungry, haven't eaten for 8-10 hours. Nothing quick to eat except milk and cereal. Wife and kids arrive while I am eating, she breezes in with the kids, cheerfully and completely ignores me, but the kids didn't, they had eaten pizza, I asked if they had any leftovers, but she didn't bring any home for me, although she knew I would be home.
They had eaten pizza with the AP, and some others, which she paid for so generously!
I didn't know there was an affair, but i thought: "Wait, we talked today, you knew I was busting my ass and would be exhausted and hungry when I got home, you bought pizza for a bunch of other people and didn't get any for me?"
During the affair actions, you as the BS become an inconvenience, AT BEST.
