Hi kd.kv,
I'd like to welcome you. I'm sorry that you're having a difficult time. I can relate how distressing that is when we're not equipped for a r/s with a pwBPD. Feelings = facts to a pwBPD whereas feelings are followed with facts for you and I, it can feel like crazy making behaviors to the non disordered partner. You're not alone. You'll find many members here that can relate with you and offer you guidance and support.
i keep please reading things up, the smallest mistake and i go from hero to zero and i don't know i'm making a mistake until its too late. how do i avoid this?
A pwBPD see people and the world as either all good or all bad and don't ser the two as an integrated whole with people. So, you're either a hero or a zero with np in-between. My advice is to read as much as you can about the disorder, you will quickly see the benefits and become proficient over time.
Maybe you're making mistakes, don't be hard on yourself, as I was saying your partner will vacillate between hero and zero, it's a BPD behavior called splitting, it's bot personal to you, it's not something that your partner can control or that you can control, it helps to identify the behavior, become indifferent and know that it will eventually pass. Welcome to the family
