I just can't believe how he passively threts me all the time and want us to be friends?
That's because a borderline hates to lose an attachment, it's the worst thing that can happen, a dysfunctional attachment is still an attachment, and the only one to sever it is you, which it sounds is what you want to do.
You can take a lot of the confusion out of his behavior by learning about the disorder Dontknow. That won't make the behaviors any less intolerable or unacceptable, but at least you won't be confused, and that helps a lot. Plus, he can even become a little predictable once you learn his motivations on a clinical level.
Yes that's why I love this site, it helps a lot. I seen other people in the same situation only steps ahead and it's crazy how I'll read about something in someone else's life and a week or 2 later it happenens to me.
For sure I need to research more so I won't be as shocked also know that for sure I'm making the right choice that he can't get full custody. I see him mentally messing up our son.
Thank you, more research for sure
