Hi Gemini 41,
Welcome to the family!

There are a lot of great tools you can use here to help you relate to someone with BPD or BPD traits. You might like to read the Success Stories at the top of this board:
https://bpdfamily.com/message_board/index.php?topic=113820.20 I've been reviewing them today and they are giving me lots of hope.
I am not sure if you have seen the
Basic Tools and
Lessons on the right hand side of the board yet, but there is a lot of great stuff there. One of the best basic things you can work on, many of us find, is to not be invalidating. (The Tool is:
Don't be invalidating https://bpdfamily.com/content/communication-skills-dont-be-invalidating )
Let us know what you think!

Is this something you'd like to try?
