I'm sorry that you had to go through such experience.Do you know how long it takes to be assessed ? Have you seen anyone successful?
It may take some time before IMMI get back to you, and if it isn't favourable , i,e., visa refused, you can take it to the tribunal for appeal. I'm not sure how long the process will take. Varies i guess from case to case.
But you've done everything you can for now, just, have faith, and patience. The case i had to go through was even more difficult to prove as it was family violence but not physical, it was psychological violence. Took almost one year for tribunal to hear the case , and decision was after 5 months.
I wish you the best
