If something happens that pisses her off and you genuinely care and wanna find out and fix it, how do you do it? Are you even supposed to do it?

Asking about it is clearly fruitless.

EDIT: thanks for all the creative replies guys! I'm sure I can use more than a few from them. Problem was: I wanted some personal space so I went off the radar 1 day. The next day we meet and she's silent, answers straight to the point to whatever I ask and initiates no contact/ communication.

I was in a rough patch that day (yesterday), so I was down to 0 with my patience and started nagging her to tell me wtf was wrong. Eventually she gave in and said that maybe she's a bit tired and she's trying to reciprocate my behavior from yesterday.

I took a mental note about it and then brushed it off like nothing happened. Subject was closed and it remained in the past, but it took a solid 2H of texting and 30 mins face-to-face to get it out of her and over with.

Sorry for not being that specific initially but this unrolled right after I posted this thread. I appreciate any solutions that you'd give now that you know the full thing. Thanks in advance!
