Hey Girl, insecurities run wild with almost everyone walking this earth. Your mother had shown love, the ability to try and seek the truth within you, however, she too is insecure and perhaps will choose to stay and obey her demons and the man she confides in.
Everyone has a potential to love unconditionally, but instead of just doing so, first they must get arid of their own demons, this proves on and on to be harder then just saying it. My own birth father had disowned me, a 44 year old child at the time, because of his own guilt and insecurities. It is hard to process such rejection as its mechanism seems out of this world, but it happens every day to hundreds.
Your truth however, is you OWN path, not theirs, in that you will find pain but also great joy!
All my love, Inna
