Is that how you see her? Remember how it was when she was free and lovely? Well she is still there. Just overwhelmed by her life, by the changes, by the needs of the baby, demands probably throughout every night with crying etc, -do you help out? Try doing it with love not resentment. Your life includes a son or daughter. That is amazing. Bring some joy into your marriage, some positive stuff. Hire a sitter. Go out for dinner, tell her she is wonderful, and babysit for her so she can have a nap. She is barking out orders and unhappy because she can really tell you are wanting to run, you hate the changes in her, and you are not there to understand what she is trying to tell you. Hormones for one. They are through the roof right now, anything can set her off and this will change to normalize soon enough. She does probably have some post natal depression which is common and it is brutal. Don't take everything she does and say personally like it is an attack, it will save your relaltionship. It will pass. This soon will pass, tell yourself. She wants to get back to the way she was, believe me. She will, too, once again be positive -she will get her energy back with medical help for the depression, your loving words and kindness and sleep. This is not about you right now. Giving birth is hard gruelling for months and months for some, and for some it is a breeze. Take care.
