Me (M50), my whole life, my Mom( F75)has never respected boundaries.  Anytime my girl or I ask her not to say things to anyone,  she tells people.  She's asked a number of times about when we are getting engaged/ married.  I've told her we will do it when we are both ready.  She kept asking even after we've asked her not to ask about it.  Stuff like that, or we share something and tell her to not tell anyone else, but she talks about it to other people.  

When we tell her we are upset she did that, she says she's sorry and it won't happen again.  But she keeps doing it.  She's done this stuff her whole life and will not stop.

We've told her we don't want any contact. We've blocked her on our phones. But when she passes,  I don't want to even do anything about services.  

Am I going to far?
