I was in a relationship for 4 plus years, only towards the end was I abused, and the very end totally abused and violated, I also had very sentimental things stolen from me, plus money and other immaterial things. In the end you just have to let things go, you can replace material things, although the sentimental things are irreplaceable, but your moms safety is more important than anything and you are a great daughter, just stick in there together and good luck.
