And the whole not going to have contact for a day or two and take time for myself, how did that work out?
I'm with the others; what the hell is she doing? Clearly neither one of you mentioned the conversation with her parents and of course, you know not to vent to in-laws. And I'm guessing her stuff is still there and she still has access to the house?
I guess I don't understand the part of her inviting you places, then coming over, hanging out, leaving and coming back. This is behavior just like a couple.
I can sense and understand your frustration.
And you have not taken the time to step back from the situation and analyze each other's actions.
I really don't think there is going to be any shift in the dynamic, behavior or actions, until there is a chance to step away and REALLY clear your head.
