The financial bubble burst pretty quick sometimes after they move out . Once reality sets in that he now has to support himself along with the W he left and kids . My H has never been involved in paying bills . Keeps certain amount of money from each check . He continued to try to pay his share of my household and live outside the home . He constantly ran out of money from not managing it properly while living on his rollercoaster. I left no more than a $100 in our joint account and every pay he moved money in and texted me . Within minutes I moved it to my single account . They promise the world but Never trust it . Yes separate your funds if he’s moving out .
