Should I mention Parental Enmeshment and then what?

My new partner "seems to me" to be emotionally entangled with parent. If my partner is on the phone with that parent I MUST BE TOTALLY quiet or they will "get in trouble". I said "That is just ridiculous, for God sake." My partner says they know it is ridiculous and I'm sure I am not the first to ever mention this.

Now, even if my partner is AWARE of this (I believe counseling has occurred due to it in the past as well) - should I bring these things up when I notice them? Or only say it in context to "How it makes ME feel" not so much to JUST fix them? (Not just the phone calls because that is VERY obvious already)

It has been difficult to sort out/bring up at the moment because the partner is also facing a lot of physical pain (recent surgery) and is taking meds due to this pain so I am not always sure what is "emotional" stuff or what just looks like it due to pain meds, and is it right for me to even say anything at the moment when depression is also involved?

We weren't together long before this surgery which has had a pretty long recovery time which helps deepen the depressive states as well (and thinking may not be so clear)
