Advice from the old lady:
She likely does not realize it bugs you. So if I were you I'd mention it and give her the opportunity to correct the behavior.
That way you can respect yourself and also continue to enjoy her physically.
This is something that can really vary from person to person. Some people are open about past experiences as an opportunity to get to know their partner...others are not. But that kind of dialogue or personal disclosure requires mutual trust and investment. It also requires a setting aside of ego and maturity. Great lovers seek to tailor the experiences for their partner and use information they learn about the partner to accomplish this. So what she shares may be in an effort to help you know & understand her.
Communication is not a "beta" behavior. Good communication honors you, gives you opportunity to speak your truth, and is actually a hallmark of leadership and maturity, which are "alpha" characteristics.
Communication is also a 2 way street. Great lovers have a depth of connection in addition to crazy physical chemistry. Mutual open communication is a foundational attribute to connection.
You need to let her know this behavior of hers bothers you & why but not in an adversarial way. Not in the bedroom either. Tell her. Go from there.
I would agree with this...
I experienced this with my lady about 6 months ago...
I noticed my girl bringing up her recent ex periodically. Initially, I didn't really care, as it was sometimes in the context of the conversation, pretty infrequent (1-2 times per week), and never anything that I really cared about. More of something like "oh my brother hated him" or stupid stuff like that...
Then one week, I noticed a bit more, so I just put it to rest. "Listen, I don't really care to hear about your ex..." then I explained how it's us now, and I believe it is disrespectful and the behavior needs to stop...
She was floored. She responded with "I thought you didn't care. I am so sorry..." she apologized daily for the next week or so, and I haven't heard more than an occasional peep (once a month) since.
Non-chalant IDGAF attitiude is a bit of a double-edged sword, women end up believing you really don't care about most things, so they free themselves around you. The trick is to keep their communication open, but help them understand the boundaries.
This is the answer here...
This is also a good test to see how she reacts to your justified concerns..
If she gets defensive, argumentative, blaming etc, then you know your dealing with a bad apple or possible narcassist here..
If she reacts in a negative way, do NOT get angry.. Do NOT argue with her..
Simply watch, listen, observe, then later DUMP her ass.. You do not want a woman who disregards your feelings and concerns.
Watch how she reacts!
