AML No, you can't scream but I know you want to. You can type in CAPS here instead LOL! We all get in that headspace - you're not alone.
So does that mean she isn't coming home at all tonight?
And it wasn't stupid to ask if she wanted to know where you are going - she seemed to be digging at you on your behaviour.
Why would she feel she needs to tell you? Did something happen in the past that you don't/wouldn't trust her?
What's a honey do? If it's some H/W R thing then she is definitely giving you mixed messages and you know - none of what they say and half of what they do...
As for the physical 180 - has she told you not to touch her at all?
Detaching is NOT being cold, ignoring etc We do it for us so that we can be calm, not to punish/harm relationship. It is about not taking all she does/doesn't do, says/doesn't say personally. If we are detached from their actions, we can respond from a place of love and honouring them in who they are, rather than reacting because our ego is wounded. It means we accept their choices/actions (unless it infringes a boundary) and let it wash over us (you are getting better at this). It also enables us to be cool when something positive happens. We are "charged neutral". It means being detached from any outcome of our actions too. No expectations.
HTH
Aside. Sometimes I wonder how households run like this esp with children. That folks just tell the other what they're doing and expect the other to deal with it. What if you had plans that you hadn't mentioned either? It isn't respectful by either party in my opinion but that's just me.
