One more quick thing..... I hear you and I respect your side. It has to be very difficult for you to always hear about the past. Like I suggest in my other reply, maybe you could find a way that you are both getting what you need. Whether it be she only gets to share one memory each time, having a specific amount of time she can talk about the past, or you both agreeing to something like when you are at her house she can talk about the past but when you are in public or at your house she needs to be mindful and try to keep the past at bay?
