ML, lots of people deal with very similar situations as you describe.
For myself, I learned just beyond walking age that I would have to be the one to care for myself (make my own sandwich and pour my own Kool-Aid): my mother was never all that maternal -that trait just somehow escaped her.
I always tried to be generous with forgiveness where her short-comings were concerned, but I've had to wrestle with a few of them pretty fiercely, especially when I was much younger.

She's who she is.
And though some of those things I had difficulty in dealing with concerning her have mellowed to a level I can accept, now -I *do* still remember them, and if I let it -it could land me right back to where I was years ago in the same turmoil with my feelings towards the person she *was*, in a heartbeat.
I've exercised my right to close doors that only offer pain -and no explanation.
But things - people and
circumstances- change.
And if explanation only comes in the hereafter -I'll
certainly be ready for it.
(Smile)
For now, I make a concerted effort to accept things as they are -and leave the parts of the past that I know I can't go back and change. (That's a good way to look at the present, too, by the way.

)
And I'm all about letting time soften the sharp edges of some of those memories and experiences, and let me walk past them.
*You can walk past them, too*.
Take care.
