Thank you for the responses so far.
I read Eddy’s book and found it super helpful. I can’t keep a copy at home to reference for obvious reasons but it might be the most important book I’ve ever read.
My lawyer has a lot of experience dealing with DV, actually clocked the BPD right away without me saying it, understands his mindset and how he’s likely to respond to things, is practical and focused strongly on safety, and seems more proactive than others - for example considering if we could obtaining a proactive OOP before filing vs waiting for his reaction.
I’m documenting everything I can think of - violent and controlling behaviors, substance abuse, how the kids respond to his outbursts, daily parenting tasks/decisions/responsibilities. Our finances are a mess due largely to his impulsive spending, so I wonder if I should dig more into what is being spent and by whom, or pull up history of credit cards he’s opened without telling me, etc.
I realize I’m in a caretaker role in this relationship and I need to learn how to be assertive which is hard when I’ve been rolling over for years in order to keep the peace. So I need to work on that.
