Before my ex left me he was pressuring me to go back to work full time. He was telling me he would find me more attractive if i was more ambitious (i have a doctorate). I was working part time because my son was young and had special issues.
This was all being set up because he knew that once he left me had i been working more he would have had to pay me less in child support and alimony.
I think your husband is gone. Hes waiting for it to be more convenient for him to divorce. (Youngest is 4, hes waiting for her to be in school) And trying to play games with you to put himself in as much of an advantage as possible. He is gaslighting. Anybody would know that with 4 kids housework gets put in the back burner.
