I'm not sure if I should bring up her infidelity at this point but I am still hurt about it. I just don't get it?
I think it varies from couple to couple, and timing plays a role. What would be your intent? Would it help in your Piecing efforts? In my situation, my W speaks about the OM, but keeps herself out of it (third person). That's as close as she's going to get at this time. Our R is probably not at a point where it's safe to talk about it in detail. She talks about the past in general, but not in detail--too emotional I assume.
