Today I sent W itemized bill for what she has to contribute. it was the first time and she reacted badly. I might have nitpicked a little and possibly misunderstood the exact terms of our verbal agreement. So she mailed how sad she was, that she thought we were different and asked to meet. She was clearly upset. She then bombarded me with expenses from before we divided the money. I could respond in kind but that would only things worse. I've emailed her saying that there has been a misunderstanding and the last thing I would like is to have bad blood between us and if she wants to meet up this evening after work. I added I'm sure we can resolve it all amicably and I didn't want to upset her. I feel like any goodwill with the miss yous and can we meet up will have been lost and she'll have spent the day crying to OM about her husband and how she made the right decision to leave. Feel terrible
