I'm not in much of a position to give advice, but you have to settle in for the long haul. My W can be pretty much the same way. She wouldn't talk and when she did, she would be all pissy and nagative about everything. Then, she would be nice, touchy feely, almost normal. That would last no more than two days and, BAM, back to super bitch. The roller coaster is brutal. I would tear myself up wondering what I said to make her go from nice to a$$ again. It is her, not you. You have to be even keeled and let her be or act however she want. Don't be a jerk, just be a good person and a good Dad.
You are not alone. Hang in there and stay strong. I am still working on all of this myself and come here for reassurance and the 2x4 when I need it. This board really does help so don't be shy and post a lot. Good luck!
