But legally if you arne't divorced its adultery... an affair...
Moving on CILVILY involves CONCENT and honesty.. He didnt' DO that did he? He HID this from you and you caught him somehow?
SOrry I have heard the "moving on" and "we're separated I can do as I please" arguments before.. I dont' buy them.
Being under different roofs doesn't dismiss the need for courtesy to your spouse... And "hey I am THINKING of putting myself on the market.. are YOU OK with this... are we DONE?" IS in order for a separation...
We have many people on this forum who have encountered infidelity during separation... even some WS on here who started teh affairs during separation and ADMIT it WAS an affair and even FELT like one.
Sorry, but I dont' buy it.. if you are giong to argue your h's case for him then why fight it?
