Sometimes a natural consequence feels like punishment, sometimes like reward.. it depends on the actions that created the consequences.
If she wanted a loving and sweet relationship with you in her old age, then she needed to put the time and effort into that.
If you want a loving and sweet relationship with her, then you'll probably have to allow her to live in denial and support the fantasy for her.
If you want justice, you won't get it. If there is something that will make you feel secure in the world... that would probably be boundaries. One boundary I have now, is reality. If people don't live in reality, I don't want them around me. I find them to be cowards and highly gullible, and they often seem to have a predator in their midst. They spend my time obligating me further to them, instead of bonding with me.
So, the people who think that I am interested in punishing my parents are just wrong. It may feel like that, even to me sometimes, but I think that is because I have lived life from my parents' perspectives for so long that I see their side of it before I see my own. And, that's a huge problem. It's much easier to have fun in life when I see life from my own perspective. I'm not trying to hurt anyone, I'm just trying to live my life in the truth.
If they want to do that too... I would embrace them! I would welcome them to it! I would feel so sorry for them and the pain they are about to experience in accepting the choices they made which led to such disastrous results! But, they don't want that. They want a free pass. They want ME to do all that work... and let them skip it. That's not only unfair to me, it's unrealistic and destructive to my psyche. Not to mention the fact that since they aren't going through the work themselves, they have no appreciation for how painful and arduous it was to get to the point I'm at in life now! To accept it... that took so much out of me. :( I just have no respect for those unwilling to go through it in order to have a relationship with me.
I'm not chop suey. :) I'm an incredibly loving, kind, intelligent and brave person! They should get to know me! But, that isn't their choice. I have come to the point where I can explain this stuff to them in a calm tone of voice, and still hang up the phone saying "I love you." It's rare that they call me anymore. They don't like hearing it explained. And, they are grumpy when I ask them if they've been to counseling... "Me? What for?" "I'm fine. Isn't it up to me to decide if I need help?"
"Well, you haven't been able to repair your relationship with your daughter.... in 10 years... don't you think they could help you with that?"
And, that's when they start putting it back on my shoulders... All my fault that the relationship fell apart. So, I tell them I love them and hang up the phone. Fortunately, this doesn't happen much.
Good luck with your therapy. It really is a matter of changing your mind. Lots of stuff gets "decided" when you're a child... and you think it "has to be" this way... or else... ?... Changing your mind about those decisions can really help you get passed a lot of the anger toward your mom and siblings and Aunts.
