I would just stand your ground about giving space and maybe a separation is what is needed. I know when I move out I told him I was going to file for legal separation and then I didn't but he did file for divorce in July but told me he didn't want to set a court date for a year. About 3 weeks ago him and the OW got into a fight and he sent me an email the next day with the financial paperwork to complete to continue with the divorce and I just sent back we agreed one year. I still haven't sent it back and not planning on it. He can't afford a divorce lawyer. Now he quit school and this weekend moved in with her and her 6 kids.... This won't last... 6 months at the most!!!
