Yes sweet nightdream, that has been mostly my experience as well
With my former therapist too
Although there have been some exceptions like with my husband and a few friends (I am not sure if I am close to them though, probably not.... depending on what you mean by close!)
I think sometimes I hope for too much....

(And care too much as well)
(And sometimes the harder I try the more I "fail"

...)
There are lessons to be learnt though....
Yes, healthy boundaries.... I believe they are possible for almost everyone... eventually.... so long as we try.
But there are a lot of scraped knees and even broken hearts along the way for some.
I know your pain
Love,
Fuzzy
