I suspect you could have an issue. You are in contact with her. She isn’t in prison, I didn’t see anything about documented physical abuse or restraining orders in your post. It sounds like they are not divorced yet. You wouldn’t be the only student with a parent who could pay, but refuses to.
I am not sure what Questbridge will ask for, but colleges that give good aid will want her info. You can apply for a waiver at each college, but you may not get one. I’d try to pare this info down a bit - the gritty details are probably too much info for the colleges.
Others might be able to comment on complexities of filling out FAFSA with parents in the process of divorcing if one parent won’t provide info.
I think you need to make a backup plan if this derails your ability to get much aid. You might need to attend a community college. If you have high stats, there might be full ride options at colleges you may not have considered. You might want to take a gap year — I’m wondering if you might get a Pell Grant once the divorce is final? Again, someone else may be more familiar with the nuances of that.
