Hi Dellabella,
I'm not sure if there's a thread on here that already deals with the subject however since I'm new I just thought I would throw it out there
I'd like to welcome you to bpdfamily. I'm sorry that you're going through this. Many of us share have similar stories but our personal experiences are unique to us, therefor different and it helps to share with people that can relate with you.
I would find that emotionally distressing, fearful and difficult to cope with when a partner acts out then blames you for their bad behavior or threatens to cut off support, that's called emotional blackmail or FOG ( Fear Obligation Guilt )
I'm glad that you decided to join us, it helps to talk. Are you seeing a T ( Therapist ) Do you have support in real life with family and friends? Do they understand what you're going through? A lot of the behavior from a pwBPD ( person with BPD ) is behind closed doors so not many people see the acting out and we can feel isolated when people don't understand what we're going through. You're not alone.
"FOG" - fear, obligation, guilt
