Her patterns are pretty obvious. She didn't like your answers about her sleeping downstairs so she decided to piss you off by talking about custody.
This is a cycle between the two of you that must stop. Just like last week when you didn't like her answer about the money you went right to the mediator to piss her off.
Can you see how unhealthy BOTH those exchanges are and why? Can you see why it kills anything positive?
Clearly the two of you know how to push each others buttons and only you can stop. She may or may not but you stop.
Once she realized the threatening would not work she tried a new tactic - for you to feel sorry for her (ex. I feel lonely). When that didn't work she then resorted to basically telling you that you did something while you were sleeping that may or may not happened and if it *did* happen a simple apology should suffice.
Three tactics, no resolution or solution. See?
And don't tell her anything she says is frustrating you. Ignore it.
