[[[[[Virtual Hugs]]]]] for BOTH of you!
One of the things that I noticed about my own recovery from abuse was that the sense of loss was, at times, almost overwhelming. I felt that I had lost a dream, a potential partner, and years of my own life that could never be retrieved. I also noticed that the void (mentioned in a previous post) became quite overwhelming. I was so accustomed to the abusive cycles in my marriage even though I abhorred my humiliation, degradation, and dehumanization. That abuse - repellant as it was - was a self-sustaining cycle and, when it was finally broken, it took a number of years for me to replace that void with positive activities and emotions. Finally, at long last, I'm taking control of my physical Self now that I've gotten an understanding of my emotional Self.
Lakelight, I will suggest that book by Kubler-Ross, "On Death and Dying." It might sound nuts, but there is physical death, emotional death, spiritual death, you name it - and, each of those experiences is just as real as the next. There are steps of mourning and grief that we must successfully navigate in order to emerge from our sadness. This book addresses all phases of grief in a respectful, thoughtful manner - it would be a benefit for you, I believe. In fact, I feel that it should be a mandatory requirement for High School Students, at least.
It is absolutely NORMAL for you to feel sadness! The emotional support, guidance, and love of a parent was not forthcoming, no matter what you did to "earn" it and the whole thing had to be put to rest, legally, as "responsibility" and "personal accountability" were not in your mother's vocabulary! Yes, sadness is definitely acceptable, at this time - but, the danger of allowing ourselves to overindulge in our sadness is that we risk replacing the drama/trauma that the abuser orchestrated with overwhelming and, often, crippling sadness which becomes utter despair. Sadness is one thing - quite normal, acceptable, and encouraged to be expressed. Despair is a completely different thing, altogether.
This, too, shall pass, Lakelight. You will continue reminding yourself that you are not, have not been, and shall never be responsible for your mother's emotional well-being and decision-making. She has chosen to burn her bridges when she forced the legal issue - so often, it goes that way. For now, your focus will be upon your Self and encouraging your husband to heal from his part in the ordeal. At some point, you will find relief, especially when you really are able to take possession of the fact that your mother is solely responsible for her Self. Once you truly realize that, a great weight will be lifted from your shoulders - for me, it was almost a physical event!
You're just fine, Lakelight! Want2 has a wealth of personal insight and a fresh take on her experiences - keep in touch with one another because you're both emerging from a similar situation and can offer support, encouragement, and an opportunity to safely vent. God bless you both!
