Hello again, Hope2015.
It is posts like yours that keep me putting my fingers on the keyboard, reaching out to give a hug.
I echo all of what
Feeling Better writes. The part where she writes... .
"One of the hardest things is recognizing when there is no more that we can do, it goes against the grain to let go of our children ... ." ... .I will add to that... .it was so liberating for me when I did. That is not to say it happened over night... .nor is it to say I gave up being my daughter's Mother. Even at my ripe old age of 75, I have lessons to teach my 52-year-old daughter and one of the most important is that you never let yourself succumb to bullying. I was her victim for so long, reacted to each and every hurtful barb she found in her arsenal and then threw in my direction.
It was a long time in coming for me to realize that, for the most part, there is no reasoning with someone who exhibits BPD behaviours. It is a waste of time to try. In other words, don't JADE... .don't Justify, Argue, Defend, nor Explain. Work, instead, on putting into practice Tools (as seen on the right)

. It is much more constructive and empowering for... .you.
Oh yes, the estrangements hurt, a raw hurt... .especially when those innocent grandchildren are used as pawns, trump cards against us. My grandchildren are now 26/28... .both have different fathers. Because of the "magic" my daughter was able to pull off with them, neither has/wants contact with their fathers... .nor those families... .nor us, the grandparents who were called upon time and time again to be their surrogate parents because our daughter became a single parent. As a matter of fact, seems they don't even like each other. How sad is all that, huh?
Well, Hope2015, I hear you and I do recognize your pain. I do not mean to sound flippant when I say you can rise above it... .and there can be better tomorrows. I speak from my experience. Participating on this forum has helped in my healing. As
Feeling Better puts it... ."I am still a work in progress... ."... .but the key word is "progress".
Once again I direct your attention to the right

... .Lesson 2... ."If your current approach is not working, change it." You can't change your daughter... .nor your ex... .nor anyone... .but you can change you. The change in your script causes them to alter theirs.
I, too, hope you keep sharing Hope2015. We will help walk you through this and, in turn, you are going to be able to help others.
