Hi Buttercup--I have heard that the spouse of a sexual abuser was often a victim of sexual abuse her/himself and thus has their own issues. or maybe your mum feels so guilty that she didn't protect you enough that it is too painful for her to face you all right now? I am sure she is going through much turmoil but I am sure she still loves you all very much. If you don't have a T perhaps contacting a sexual abuse counseling center might provide you with more insight? Wishing you all the best. ((((Hugs))))
