Patience. That's all. She may be behaving this way because of things that you did... and/or she may be harping on points that have already been driven home with you. Either way, the only response you can control is your own. It's something I've heard a million times in recovery, and I'm sure you have too.. but it's so very true. You cannot control her - she will say what she will say, whether out of love or out of habit or both. She loves you. You are sober. Those are the things that count.
Just hang on. Things will get better. Keep on keeping on.
take care,
