No, I shouldn't have. It wasn't particularly vicious or aggressive, but still probably unwise. It expressed my frustration with the imbalance (that her "emotional support" entitled her to half my retirement while my "emotional support" plus well over $60k in tuition plus room and board apparently entitled me to nothing), confronted her with quotes from her past emails and journals (such as a year ago when she said she was only beginning to love me and would do so forever), and said that I released her from her vows so she was free to pursue her other extracurricular interests and that it wasn't my place to worry about her any more.

My mistake in thinking the deal was agreed on already. Ah well.
