FORMER significant other, still in my life because we have two children -- one of whom is a young adult having trouble launching because they are having their own mental health struggles (bipolar disorder).
Would love to go no contact, but not practical because of ongoing care/communication issues. Not that former life partner is being thorough or consistent with contact.
Am having to process the pain of discard. Even though I was very much an agent in the dissolution of the marriage, I would rather it could have been "fixed" ... .and there were behaviors/betrayals even after divorce that have made it hard for me to maintain "grey rock," since things that feel like (and sometimes are) aggressions continue.
Am to the point though where I am mostly beyond stunned and am trying to figure out how to go forward, including potentially in other relationships, but while still attending to a very active situation with the ill child.
It's becoming apparent to me that as much as I identified the things that were "off" and downright destructive, my inclinations to give space for the partner to "heal" and then mature, and to block/forget so many transgressions, mean there is a lot of painful retroactive walking through to happen, and a profound sense of sadness at wasted time, not to mention anger that I would be strung along (as it were) only to have him jump ship at a time of deep crisis and personal vulnerability. Which I know tracks with NPD (his diagnosis) and BPD, but holy cow.
Anyway. I'm pulling together how to survive financial insecurity, the uncertainty of whether and how my child will emerge through intense crisis, and a boatload of grief.
Am using lists and articles and forums like this to reinforce how on target I had been in terms of identifying issues (gaslighting and repeated downright lying take their toll). It's kind of weird, how I keep on gathering and reviewing data that support how evident patterns were and mess was, but instead of being able to say "ah, yes, so that's it" and move on, I'm -- for now, at least -- comprehending how vast the issue had built. I guess that's what twenty years in a relationship will allow to accumulate.
So... .looking ahead to figuring out how to best support my kids (yes, mostly grown, but still) as they process what happened, and how to flood my life with happiness instead of PTSD.

Now off to read the boards and see how much (all?) of this has already been raised and discussed.
