Irish, It's interesting that things were very well before the legal marriage and that they went down hill after it 4 years ago, correct me if I am wrong. I remember that my wife was very nervous when we got married. She associated our marriage with all the pain she had to endure during her parents marriage and divorce I believe. Marriage scared her very much and I didn't understand it, It was a very happy day for me. I am trying mind reading here, maybe getting married slowly contributed to your wife entering in midlife crisis mode, and now that she is not married anymore she might try to get back together and restore the family. I see her message where she says "have a good weekend and the girls are beautiful as a positive sign". It almost looks like she wants you to be aware that she will come back soon and wants to know if you and the girls are ready to accept her. More mind reading on my side.
