Wow... At least you got the truth fairly quickly...???... My AXH lied about having cancer and kept up the charade for weeks, even when he hadn't had a drink, by having me or the friend he was crashing with drop him off at the hospital campus where they do chemo and radiation therapy. He even said he had a treatment appointment the morning of DS's (then age 3) surgery, and had me drop him off at the center on my way to DS's appointment.
It's horrid finding out they fabricated something that serious. I'm sorry you had to deal with that.
