Some days are better than others

[EDF]

Wife left no message; called me via work and asked if I had a couple minutes to talk.

- She said she was sorry if she hadn't told me about the kissing before, she thought she had and she wasn't hiding it or anything.
- She said she understood how the kissing could be viewed as a betrayal, but didn't feel it was a worse betrayal than the past 17 years of me ignoring her.
- She reiterated that she was sorry but she didn't regret it, that she held off for 17 yrs and it "felt good to stop sacrificing for other people and just be in the moment". Said she probably didn't feel as guilty as she knew she should.
- She couldn't guarantee it won't happen again.
- Said she hoped I had a good day.

Just. wow. Not sure how to respond confidently to that without it coming across as an Ultimatum, or me being a doormat.
