H and I both work from home. While there are a lot of positives to this, it can be isolating, especially now after the A. I spend a lot of time by myself and can see how I tend to obsess and end up thinking some really self-punishing thoughts.
I just spoke with my mother and wow, she really cut through the crap. I was crying about TT and she said something along these lines:
It's all a variation on what you already know. It doesn't matter what time it happened or that it happened on a specific day (of course unless it was after NC) or a specific place--all that matters is that it happened. And nothing you can do, no digging for more details, no crying or harping, can change that. You can either try to make it work or you can go your separate ways. That's your choice. It hurts like hell and it's not easy, but it won't be like that forever. The OW was just a vessel for whatever was missing in H's life at the time. She could have been anyone and she is out of the picture. Time to get some confidence and realize that he wants to be with you and that you are worthy of love.
Thanks mom (a fully R'd BS herself).
