My mother is going though a very difficult for her divorce and is leaning on me heavily. I feel exhausted and I'm not performing the way she needs me to. I am not sympathetic because I think the divorce is for the best (the was DV, cheating, emotional abuse involved).
She used to speak to her mother all the time about it, but the advice there was that God has a plan and to hold on. My grandmother died 2 years ago and ever since then, I have become the person she tells everything to, regardless of whether I want to hear it or not.
I really don't want to support her. I know it's awful to admit this but I just feel so resentful that I'm being dragged into this and she's crying to me, her daughter, about sacrificing everything for this marriage and him divorcing her regardless.
I think a big reason she stayed was because of me. She wanted to keep the family together at all costs. So I feel responsible in an indirect way, just by existing.
I'm not a dick and I've been outwardly sympathetic but I'm struggling to keep up the charade.
We are not close and for the first 3 years of my life I was raised by my grandparents and only saw DM on weekends. Then when she took over caring responsibilities I was a "difficult child" so we never bonded.
I don't know how I can go on like this. But I need practical tips because surely it will all end eventually.
