Hi Alona76,
Welcome to the BPD Family

I'm so glad you've found us.
First of all what you are describing does sound very familiar, I think you will find that you have things in common with many of the members here. I hope you will read the posts of others and explore the site as you have time.
When I first discovered BPD I went to my local library and read everything they had on the subject. I found that really helpful to get a good grounding in what BPD is.
Below are a couple of books that I found particularly good... .
Stop Walking on Eggshells: Taking Your Life Back When Someone You Care About Has Borderline Personality Disorder by Paul Mason MS, Randi Kreger
and
Overcoming Borderline Personality Disorder: A Family Guide for Healing and Change by Valerie Porr, M.A.
I've also pulled information on "The Dos and Don'ts of a BPD Relationship" I thought that might be a good place for you to start (just click the link below)
https://bpdfamily.com/message_board/index.php?topic=62266.0So a few questions to get to know your situation better... .Has your partner been officially diagnosed? Do you live together? Separately? Are either of you receiving therapy?
I'm sorry I haven't more time to chat... .got to go to work, but I know other members will be along soon.
Hang in there and keep visiting us here, I know you will find support, tools, strategies, and information that can improve your situation. You are not alone in this.
Take Care
