I'm leaving tomorrow, mid morning.

I will take DD out for breakfast in the morning (there's a really nice cafe that opens early in the morning, and they make the best scrambled eggs with fetta cheese, DD and I love it), then drop her off at school, then head off after that.

I know what you mean in regards to your XH, and it will take a long time to get over. But that is normal, you two have been together for so long, you can't just switch your emotions for him off overnight.

Time heals everything. Before you know it, you will think "What the heck was I thinking?".

It's good to have your niece do the "positive vetting" on any potential partners. Sort of like the middle woman. I hope he turns out to be amazing.

I think you should go out and treat yourself on your XH's anniversary with OW. You should celebrate your new amazing life.
