I also think boundaries are important especially for us
the Mlcer will usually not follow any boundaries
you probably have tp decide if you want to continue living with her maybe you can plan more outings on your own as well and not be home when she gets back go away for a weekend ect
My XH used to get home at like 3 or 4 am many nights and then he started staying out all night He did have OW and eventually M her
He moved out and it was best because watching him drop in at 4 am was difficult on me once he left the energy in our home was better but it is a tough call some Mlcers will stay at home I hear the chances of reconciliation are better but of course it is no guarantee
No easy answer but try to take care of yourself get a hobby..make a new friend..have fun buy a new outfit visit an old friend volunteer
