it is simply rude to not even bother with paragraphs when nicely asked. some ppl also have eye and neuro problems that make reading blocks of text difficult for them, though they would very much like to be helpful.
in addition, the posters who have been turned off not merely by the unbroken text but also your replies were responders who give very good advice, especially on trauma and individuation-- both of which relate to your concern. when asking for help, simply being respectful goes a long way.
i too haven't gotten far with reading, but what is clear is there is no way you can count on having a semi-decent life with any of your family. they are beyond abusive. i don't recommend waiting on your boyfriend's family finances to improve so that they can take you in. try getting help living self-sufficiently rather than help living dependently on someone yet again.
i recommend going to your local social sevices. a social worker in direct services helps you with practical arrangements you need to get housing and live on your own, and one in clinical social work will offer counseling, any guidance required in addressing the circumstance that cause you distress, and can handle reports againts your family-- which you should file. i am not generally in favor of purely vindictive moves, but your family's behavior has me doubting they're not going to harm more people at some point.
of course the social services offer significantly less help if your financial situation allows you to live on your own (you can still use clinical social services though).
if your business isn't lucrative enough to allow you to support yourself, looking for a different job and relying on public transit would be a necessity.
