The case that I knew of, where they lived in the same house, did not have a “Happy ending”
after about a year and a half of the couple sleeping in seperate rooms, the kids started to take sides and began to take sides especially towards the mother as she was the one who slept in the living room. Shabbos was the worst as during the week usually one person could leave and not come back until coast was clear.
The woman began to go OTD (I am sure many will say “I told you so” ) as she blamed rabbis for the situtation and )Shabbos and Yom Tov were the worst days as they were more forced to be together) and she hired a lawyer (She said she was done having children and didnt care about the get anymore). She moved out and the kids spent their time at various parents homes. They both hired lawyers and now both are broke and the kids are messed up.
Nothing was gained, It would have been alot better for everyone if the get was just given and people moved on
