Please understand that PND is an illness and that she may not realise she has it. Your partner is full of hormones and they sometimes they can make her do things she would never normally consider.
I'm not sure how much you feel the relationship has run it's course but if you feel it's worth hanging on for, then please read the advice given and give it some consideration. Your partner may be feeling extremely down so a gentle gentle approach with kid gloves is needed, don't go in and confront her or make her feel even worse. Good luck with everything
