I guess it's a cultural thing. I haven't really talked about anything else than kids to my XW. Only last weekend I asked how she's doing, otherwise I haven't asked even once how she is doing because I see that as pursuing. If she talks about something I just look at her and nod, or overall listen to her. I think asking something like "you look stressed. Is that how you feel?" certainly looks odd in her eyes. We don't say that to neighbors either
