Why is she keeping them from me?

Yes, you will get screwed (in ways and positions you never would have thought of)

The degree to which you get don't screwed depends on how much advice you make use of.

I never left my home, my stbx left me and took my S8 with her to her parents place.

Get back to the house before there's a hearing that gives her exclusive use and posession of the home (and makes you pay every dime you earn while depriving you of legal counsel and necessities of life while the litigation is pending).
