Hi Bruno250, welcome to the group -- you're doing a positive thing by reaching out for support and education as you decide what you want to do.
Joaquin made a great suggestion; the book
"Stop Walking on Eggshells" has helped so many members here have healthier boundaries and healthier interactions with pwBPD (people with BPD).
I see you posting here on the "Bettering a Relationship" board; am I tracking with you that you would like to repair the relationship?
I also am reading that you're realizing that
I want to know what I can do to save this. I want to understand what I can do to help her I miss her. But also I’ll be ok with or without her. But I want her and only her. We were together for 4-5 months. I don’t know what any of this means
It's OK to be in the place you're in, where you're working through a lot of those feelings -- I want to save this, I miss her, I'll be OK without her, I want her, but what does it all mean. pwBPD struggle with having managed/regulated emotions, a sense of identity/self, and appropriate boundaries, so sometimes that can spill over into their romantic relationships -- you, too, end up confused, all over the map, and feeling intense emotions.
While we can't predict or guarantee the outcome of any relationship, what I can say is that working on yourself, working on your own mental health and boundaries, is one of the best ways to have a better relationship. When you have a strong sense of your own values, and what you are and aren't OK with, no matter what, you'll be in a better place to have the strength to have a good relationship.
Have you heard or read much about boundaries yet? Take a look at our
workshop on boundaries and values for starters and let us know what you think.
In terms of why she's talking to your mom and not you... that sounds like
unhealthy triangulation to me.
Write back whenever works for you... we're glad you're here.
