Non Rev Travel AA

Hello. I am new to this forum.
In a nutshell my mother was retired from American Airlines .
once I graduated college I began traveling on her D3 buddy passes.
Once my mother passed away my father kept traveling privileges as a survivor spouse.
Once my mother passed away making my dad a widow am I eligible to be the registered companion ?
I have continued using the D3 buddy passes. I have been flying for years now since my mother passed and have spent a few thousand dollars .
Does anyone know if I can be the registered companion ?
Thank you.
