Exactly, she told our mutual friend she knows I'm sleeping with, OM's ex....! I was like WHAT.... where in any universe does that make sense. Lol, talk about left field, and gross. I just have to keep doing me, and take care of myself. She can accuse and make assumptions all day long, everything comes out in the wash sooner or later.
Sometimes it doesn't matter if the WAS is lying or not because some friends will perpetrate like the lie is the truth. Depends on the group of people. SO yes. WAS could lie on you and you pay for some things you didn't even do.
