I can understand your situation its really weird. I guess her behavior is like that, which you need to talk about when she is cool enough. You can do one thing, maintain a note about her on what matter she was yelling on you. And when she is cool talk to her about your daughter how much you both are important to her, and ask her the reasons. Also I guess your love relation has lost its spark, which you need to work out to bring back, so that everything normalize. And if needed take professional help. Hope everything will be fine with you.
