So, the title kind of explains it. She was diagnosed about 6 months ago. The symptoms she mostly focuses on are quick irritability and promiscuous behaviors. When she is having a bad day, I try my best to be there for her and give her advice that's not too harsh. What I've noticed lately, and I'm not sure how long it's been going on, is that she constantly finds something to be upset over and she is constantly cheating on her husband and using the symptom mentioned above as an excuse. She's quick to invalidate anyone else who is having a "bad day" and instantly turns it around to talk about her problem. Is there any way I can get her to realize she is becoming a toxic person without absolutely crushing her or should I try for the blunt and honest approach?
