Getting out of the house while she's home means giving up time with my daughters, so it's tough to stay out of her hair.
Also, I wonder if she's having an EA with a coworker. The OM is in a longterm relationship, and will be moving out of state in the next couple of weeks with his GF. My W frequently cooks food and takes it to work to share with him; she also talks about him a lot, though she talks about a lot of her coworkers too. She doesn't have much time for any type of hookup, though she is working out in the mornings around 5AM at the Y. So that could just be a cover; I'll have to do some detective work to see if she's really going there or having a rendezvous.
